1330200 玖、發明說明: 【明戶斤屬軒々貝 發明領域 本發明係關於一種可形成HBV病毒之類核粒子的HBV 前核蛋白。 I:先前技術3 發明背景 病毒感染之診斷主要是利用檢出病毒和病毒關連成分 (蛋白和核酸)的方法和,測定生物因病毒感染所產生的特異 抗體之方法來進行。在B型肝炎病毒(HBV)感染中已導入 HBs抗原/抗體、HBc抗體、HBe抗原/抗體、113¥一1^八等 之診斷標記故為臨床檢查法。 通常,有無感染HBV可以利用HBs抗原和HBc抗體來偵 知。另’不僅HBV之感染性,HBe抗原/抗體、HBV —DNA 量之測定也被用做為HBV帶原者之病況和癒後、治療之效 果判定的指標。其中又以HBe抗原/抗體免疫測定法因操作 簡便且價格便宜’應用最為廣泛,惟在無法產生/分泌HBe 抗原的前核變異株中,因為HBe抗原即使為陰性,HBV的 增殖依然旺盛,故存在感染性和免疫原性強且病態亦相當 活動的病例。另一方面,不論野生株或變異株,反映HBV 之增殖/複製狀態的HBV —DNA量之測定雖然重要,惟有前 處理法和測定法繁雜,且缺乏再現性和安定性的問題。1330200 玖, invention description: [Minghujin Xuanyuanbei invention field] The present invention relates to a HBV pronuclear protein which can form nuclear particles such as HBV virus. I. Prior Art 3 Background of the Invention The diagnosis of viral infection is mainly carried out by a method of detecting a virus and a virus-associated component (protein and nucleic acid) and a method of measuring a specific antibody produced by a virus infection. In the case of hepatitis B virus (HBV) infection, a diagnostic test for HBs antigen/antibody, HBc antibody, HBe antigen/antibody, 113 yen-1, and the like has been introduced. In general, the presence or absence of HBV infection can be detected using HBs antigen and HBc antibodies. In addition, not only the infectivity of HBV, but also the measurement of the amount of HBe antigen/antibody and HBV-DNA is used as an indicator for determining the condition of the HBV-bearing person and the effect of the treatment. Among them, the HBe antigen/antibody immunoassay is simple and inexpensive to use. It is the most widely used, but in the prokaryotic mutant which cannot produce/secret the HBe antigen, since the HBe antigen is negative, the proliferation of HBV is still strong, so There are cases where the infectivity and immunogenicity are strong and the pathology is quite active. On the other hand, regardless of the wild strain or the mutant strain, the measurement of the amount of HBV-DNA reflecting the proliferation/replication state of HBV is important, but the pretreatment method and the measurement method are complicated, and the problems of reproducibility and stability are lacking.

最近,無論是在HBV核關連抗體(HBc抗體及HBe抗體) 的存在下或變異株的出現,均已開發出被認為是反映HBV 5 1330200 之增殖/複製狀態的HBV核關連抗原測定方法。Kimura等 (Journal of Clinical Microbiology, 40,439 — 445,2002)採用 對HBV關連抗原(含有HBc抗原及HBe抗原之HBV前核/核 遺傳基因產物)具有特異性的單株抗體,透過簡便的前處理 法,開發出同時檢測血清中之HBc抗原與HBe抗原的免疫測 定方法,顯示具有和檢測出病毒基因組(virus genome)的 NTA檢查法相關之情形。 在目前為止的文獻報告中,HBV前核/核遺傳基因編 碼由全長212胺基酸殘基(胺基酸序號:—29〜183 (以HBc 抗原的第一個胺基酸為1。以下相同))所構成的蛋白質,在 其N末端上具有19殘基之訊息肽(signai pepti(Je)。所稱訊息 肽係由疏水性的胺基酸殘基構成,其功能係做為分泌蛋白 用以結合於膜的訊息序列。此處係指第_29--11胺基酸 所構成的序列。Recently, HBV nuclear-associated antigen assays have been developed which are considered to reflect the proliferative/replicative state of HBV 5 1330200, either in the presence of HBV nuclear-related antibodies (HBc antibodies and HBe antibodies) or in the presence of variants. Kimura et al (Journal of Clinical Microbiology, 40, 439-445, 2002) use a monoclonal antibody specific for HBV-associated antigen (HBV pronuclear/nuclear genetic product containing HBc antigen and HBe antigen), which is simple before The treatment method has developed an immunoassay method for simultaneously detecting HBc antigen and HBe antigen in serum, and has been shown to have a relationship with the NTA test for detecting a viral genome. In the literature report so far, the HBV pronuclear/nuclear genetic code encodes a full-length 212 amino acid residue (amino acid number: -29 to 183 (the first amino acid of the HBc antigen is 1. The same is true below) )) The protein consists of a 19-residue message peptide (signa pepti (Je) at its N-terminus. The so-called message peptide is composed of a hydrophobic amino acid residue, and its function is used as a secreted protein. The sequence of the message bound to the membrane, herein refers to the sequence consisting of the _29--11 amino acid.

别核蛋白一經譯碼即通過内質網膜,19殘基之訊息肽 切斷後,(:末端㈣結合區被切斷成為版抗原(胺基酸序 號.一10〜149),分泌到血液中。過去,該HBe抗原被認為 是在血液中與白蛋白和γ—球蛋白等之血清蛋白結合而存 在’尚無形成HBV粒子的報告。另,HBe抗原雖亦有與免 疫耐觉性之維持、病毒複製之抑制等有關的報告,惟就HBV 之複製而。並非不可或缺,其生物學角色不明的部分仍多 〇 W核/核遺傳基因具有第2個轉訊起始訊息, 被該起始訊息所轉譯之產物形成版抗原(胺基酸序號:i 6 1330200 〜183),一邊將HBV前遺傳物質RNA納入一邊形成病毒蛋 白鞘(virus capsid),於套上由HBs所形成的外套(envelope) 後,即以完整的病毒顆粒(Dane particle)形式被釋放到細胞 外。雖然已有該HBc抗原當中若存在第1_ 144胺基酸,就 會發生核粒子的形成,惟形成感染性病毒核粒子的分子被 認為是由第1 一 183胺基酸序列的蛋白所構成。 如上所述,HBc抗原與HBe抗原既為具有大部分共同的 序列之蛋白質,同時又具有大相逕庭的性質。對該性質上 之差異產生主要作用者乃HBe抗原之位於胺基酸第一7號 的半胱胺酸殘基。該半胱胺酸與相同分子内之第61號胺基 酸的半胱胺酸殘基形成二硫化物結合,獲得e抗原性(M. Nassal and A. Rieger, Journal of Virology, 67; 4307-4315^ 1993)。從如果施以使第一7號之半胱胺酸變異成其他胺基 酸等之處理,導致無法形成該二硫化物結合,即無法獲得 HBe抗原之構造的事實,亦顯示出該二硫化物結合之重要 性。 另一方面,HBc抗原因係自第1號胺基酸部位開始被轉 譯,故不具有位於胺基酸第一7號之半胱胺酸殘基,獲得 HBc構造;2分子的HBc蛋白利用第61號胺基酸之半光胺酸 殘基相互間形成二硫化物結合而形成均二聚物,形成病毒 蛋白鞘(核粒子)。 存在HBV患者血清中之HBV核關連抗原大致區分為, 主要構成具有感染性之Dane顆粒的HBc抗原(胺基酸序號:【 〜183),以及,雖然與HBc抗原在胺基酸序列上幾乎相同, 7 1330200 但是抗原性與HBc抗原不同之分泌性HBe抗原(胺基酸序號 :—10〜149)。然而,TAKAHASHI等(Journal of Immunology, 147, 3156-3160, 1991)業已指明其他顯示出HBe抗原性之前 HBe抗原(胺基酸序號:一29〜149)在血液中成為次要分子 的存在。 其等將混合血清以超離心加以分離,從上清液以抗 HBe單株抗體之親和性管柱精製出具有HBe抗原性之蛋白 ,並決定其序列。HBe抗原蛋白質係如前所述,被認為並 未形成病毒顆粒地存在血液中。其等亦在未實施剝離(破壞 )HBV的外套蛋白,即HBs抗原之處理,或類似破壞病毒顆 粒、核粒子的處理之下,決定了所精製成之原序列 :具有其等所證明之訊息序列的HBe抗原(胺基酸序號:一 29〜149)被s忍為係游離於血清中地存在著。 再另一方面’雖已有報告指出Dane顆粒中存在著不含 — DNA 的空粒子(SAKAMOTO et al. Laboratory Investigation, 48, 678-682, 1983)和含有受到剪接之較一般 為短的HBV —DNA之無法複製的缺損粒子(TERRE et al Journal of Virology,65, 5539_5543, 1991),惟並未進行形成 該粒子之HBV蛋白的詳細解析。 就這樣,在該等文獻中所解析之血中HBV核關連抗原 的生化學分析無法稱為充分之下,被認為是反映HBv的增 殖/複製狀態之HBV核關連抗原的病毒標記在血中的存在 形態就一直這樣維持著未解明狀態。 【明内容】 8 1330200 發明概要Once the nucleoprotein is decoded, it passes through the endoplasmic reticulum membrane, and after the 19-residue message peptide is cleaved, the end (four) binding region is cleaved into a plate antigen (amino acid number. 10-10-149) and secreted into the blood. In the past, the HBe antigen was thought to be present in the blood in combination with serum proteins such as albumin and γ-globulin, and there was no report of the formation of HBV particles. In addition, although the HBe antigen is also maintained with immune tolerance, Reports related to the suppression of viral replication, but only for the replication of HBV. The part of the biological role is still unknown. The W nuclear/nuclear genetic gene has a second start message. The product translated from the beginning of the message forms a plate antigen (amino acid number: i 6 1330200 ~ 183), and the HBV progenitor RNA is incorporated into one side to form a viral capsid, and the jacket formed by the HBs is placed on the jacket ( After envelope, it is released into the cell as a complete virus particle. Although the first _144 amino acid is present in the HBc antigen, nuclear particle formation occurs, but an infectious virus is formed. Nuclear particle The molecule is considered to be composed of a protein of the first 183 amino acid sequence. As described above, the HBc antigen and the HBe antigen are both proteins having most of the common sequences, and at the same time have very different properties. The main cause of the difference is the cysteine residue of the amino acid No. 7 of the HBe antigen. The cysteine acid forms a cysteine residue with the amino acid 61 of the same molecule. Sulfide binding, obtaining e antigenicity (M. Nassal and A. Rieger, Journal of Virology, 67; 4307-4315 ^ 1993). From the application of the first 7th cysteine to other amino acids The treatment, etc., resulted in the inability to form the disulfide bond, that is, the fact that the structure of the HBe antigen could not be obtained, and also showed the importance of the disulfide bond. On the other hand, the HBc resistance was from the amino acid No. 1 The site is initially translated, so there is no cysteine residue located in amino acid No. 7 to obtain the HBc structure; two molecules of HBc protein are formed by the semi-photoreceptor residues of the amino acid No. 61. Disulfide combines to form a homodimer, forming Toxic protein sheath (nuclear particle). HBV nuclear-associated antigen in the serum of patients with HBV is roughly divided into HBc antigen (amino acid sequence number: [~183), which mainly constitutes infectious Dane particles, and, although with HBc antigen Almost identical in the amino acid sequence, 7 1330200, but the secretory HBe antigen (amino acid number: -10 to 149) which is different in antigenicity from the HBc antigen. However, TAKAHASHI et al. (Journal of Immunology, 147, 3156-3160, 1991) It has been indicated that other HBe antigens (amino acid number: one 29 to 149) appear to be secondary molecules in the blood before exhibiting HBe antigenicity. The mixed serum is separated by ultracentrifugation, and the protein having HBe antigenicity is purified from the affinity column of the anti-HBe monoclonal antibody and the sequence is determined. The HBe antigen protein line is considered to be present in the blood without forming viral particles as described above. They also determine the sequence of the original sequence without the peeling (destruction) of the coat protein of HBV, that is, the treatment of HBs antigen, or similar treatment of virus particles and nuclear particles: with the evidence The sequence of the HBe antigen (amino acid number: a 29 to 149) is sufficiency in the presence of the system in the serum. On the other hand, 'although it has been reported that there are empty particles containing no DNA in the Dane particles (SAKAMOTO et al. Laboratory Investigation, 48, 678-682, 1983) and HBV containing the shorter ones that are generally spliced. Defective particles of DNA that cannot be replicated (TERRE et al Journal of Virology, 65, 5539_5543, 1991), but no detailed analysis of the HBV protein forming the particles was performed. Thus, the biochemical analysis of HBV nuclear-associated antigens in the blood analyzed in these documents cannot be said to be sufficient, and is considered to be a viral marker of the HBV nuclear-associated antigen reflecting the proliferating/replicating state of HBv in the blood. The existence pattern has been maintained in an unsolved state. [Bright content] 8 1330200 Summary of invention

Carrent Protocols in Molecular Biology, JohnIn the NAT test of HBV with high clinical usefulness, there are problems such as the complicated method of PCR and TMA. In addition, due to the use of the gene amplification method, if the primer for the increase is inconsistent with the target Dna, it will cause a false negative. On the other hand, the immunoassay is simple and inexpensive to measure, but in the current HBe antigen assay as a proliferation marker, it is not possible to form the HBe antigen in the form of an immune complex in the presence of the HBe antibody. The measurement "In the case of a pronuclear mutant or a nuclear promoter variant in which the HBe antigen cannot be produced/secreted, the HBe antigen also becomes negative. Furthermore, the HBe antigen assay system has a correlation with the amount of HBV-DNA, but it cannot be applied clinically because of the complicated pretreatment and insufficient sensitivity. Therefore, the object of the present invention is to perform biochemical analysis of HBV nuclear related antigens which are considered to be clinically applicable in the screening of hepatitis B and the treatment of patients with chronic hepatitis B, and will reflect the blood of the proliferating/replicating state of HBV. The molecular species of the HBV nuclear related antigen were identified. According to the analysis thus made, it is found that a molecular species useful for diagnosis of a patient infected with HBV, and a novel diagnostic drug can be developed. Furthermore, by analyzing the existence form of HBV nuclear-associated antigen and its assignment task, it is possible to link the development of novel HBV vaccines and therapeutic drugs. The invention relates to HBV particles and HBV-associated proteins in blood, which are separated and purified by sucrose density gradient centrifugation, ELISA, electrophoresis, etc., and the molecules forming novel nucleus particles are formed by mass spectrometry. To be identified. One aspect of the present invention is to provide a HBV pronuclear protein comprising all or a portion of a message sequence having the toxic particle forming ability of a disease-like 9 1330200. The term "partially referred to herein" refers to a sequence of one or more residues from the N-terminal side among the message sequences of the 19th residue. On the other hand, the end of the HBV pronuclear protein was cut at any part of the RRRRR after the amino acid No. 150 or later. Further, the message sequence or the HBe sequence portion (amino acid number: -10 to 149) may also contain a variation' as long as the allowable variation is in the range in which the nucleation-like particles can be formed. Preferably, the HBV pronuclei protein is a polypeptide formed from the amino acid sequence of SEQ ID NO: 1. Further, the present invention provides HBV-like core particles or hbv-like virus particles formed by the above HBV pronuclear protein. Further, an HBV diagnostic drug or kit comprising the HBV pronuclear protein, or HBV-like nuclear particles composed of the protein, and HBV-like virus particles is provided. Further, a method for measuring the HBV pronuclear protein, or a diagnostic drug or a diagnostic kit is provided. The HBV pronuclear protein assay may also include the step of exposing the HBv pronuclear protein and the step of binding the HBV pronuclear protein to the recognition probe. However, the step of exposing the HBV pronuclear protein may also be the treatment or addition of the surfactant. The activity of the interface is not limited, and the nonionic surfactant is also effective. The ionic surfactant is particularly suitable. However, when a diionic surfactant is added to an anionic surfactant, further addition of a nonionic surfactant is effective. Further, the probe which binds to the aforementioned HBV pronuclear protein may be combined with the sequence probe of the amino acid number - 28 to 11. The bribe can also be 10 1330200. The anti-HBs antibody is used for immunoprecipitation. By measuring the HBV pronucleus/nuclear protein in the sediment, it is also possible to specifically measure only the particulate HBV pronucleus from which the free HBe antigen has been excluded. / Nuclear protein. This immunosuppression can also be replaced by separation using a probe that binds to the Η B s antigen. According to the above measurement method, when the measured value of the HBV pronuclear protein is included in the measured value of the HBe antigen, the value of the particulate HBV pronuclear protein in the sample can be calculated by subtracting the measured value of the HBe antigen. Determination. Further, the correct value of the particulate HBV pronuclear protein in the sample can also be measured by subtracting the measured value of the HBc antigen from the value. The quantitative value of the determined particulate HBV pronuclei protein can be used as a pathological marker for HBV infection. Further, the present invention provides an assay kit comprising an anionic surfactant and an antibody recognizing the amino acid of the _28 to 15 〇 amino acid of the HBV pronuclear protein, and a diagnostic drug comprising a kit for measuring the HBe antigen. Other aspects of the invention provide HBV vaccines and therapeutic agents comprising HBV pronuclei. In addition to the above, the present invention provides methods for assaying antibodies against particulate HBV pronuclei, or diagnostic agents, diagnostic kits. In the above, the above-mentioned HBV pronuclear protein particles can be used as an antigen. The particles can be purified from density gradient centrifugation, immunoprecipitation, etc. by using a serum such as a density gradient centrifugation or an immunoprecipitation, and the HBV pronucleus can be obtained by removing the coat with a surfactant or the like. The protein antigen is exposed. Alternatively, a recombinant protein can be used to produce a particulate hbv pronuclear protein. By using this antigen, it is possible to measure an antibody against the particulate HBV pronuclear protein which is different from the HBc antibody and the HBe antibody.

[Embodiment 3] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail. A newly identified HBV pronuclear protein in the present invention refers to a protein comprising a message sequence and which can form a viral particle such as HBV. The protein of the present invention in blood, whose main molecule is a p22 antigen formed by auricular abundance of 22,000 amps. A representative amino acid sequence of the p22 antigen is similar to the antigen of the HBV pro-nuclear antigen formed by the 178 amino acid described in the Sequence Number. By obtaining an antibody that specifically recognizes the antigen and combining the pre-treatment methods to construct a measurement system, the HBV nuclear-associated antigen can be measured even in the presence of an antibody. Often referred to as HBV pronuclei/nuclear proteins are HBe antigens (HBV e proteins), HBc antigens (HBV nucleoproteins), and other HBV pronuclear/nuclear gene products. In the case of "HBV pronuclear protein" as used in the present invention, unless otherwise specified, it means a Hbv pronuclear/nuclear gene product, i.e., a protein, which contains a gfl sequence and has particle formation energy. The protein shown in the sequence listing is a representative example thereof. Further, "HBV nuclear-associated antigen" means a HBV pronuclear/nuclear gene product containing HBc antigen (HBV nucleoprotein) and HBe antigen (HBV e protein). 13 1330200 Firstly, patients with hepatitis B were also separated by sucrose density gradient centrifugation. When measuring HBV nuclear-associated antigens in each fraction, a peak was detected near the same density of 1.05 as the HBe antigen, at a density of 117. Another peak can be detected in the vicinity of the separation portion which is substantially identical to the HBc antigen and HBV-DNA. If the peak near the density 117 is further separated by a low gradient sucrose density gradient centrifugation, the HBc antigen and the HBV-DNA show a peak in the same fraction, but the HBV nuclear-associated antigen will be slightly lower. A peak is shown in the separated portion of the density, and a virus foreign protein, that is, an HBs antigen, can be detected in the separated portion. That is, in the serum of patients with hepatitis B, it is considered that in addition to the Dane particles showing the susceptibility, there are viroid-like particles formed by a slightly lighter HBV nuclear-associated antigen. Further, if the fraction containing the particles formed by the HBV nuclear-associated antigen and the Dane particles is subjected to gel filtration, the HBc antigen and the particles formed by the conjugated antigen are separately eluted into the empty body fraction. @, If the same fraction is treated with Nonidet P-40 (NP~4〇: Naealai Tesque), the HBs antigen of the protein is stripped and then condensed and filtered, and the HBc antigen and the antigen associated with HBV are formed. The particles are likewise dissolved separately into the hollow body separation portion. This case shows that the HBc antigen and each particle formed by the HBV-associated antigen are formed, and the strong protein sheath structure is not destroyed even if it is treated with a surfactant which can strip the HBs antigen of the protein. Secondly, from the analysis of the Western blot method, although the HBV nuclear 14 1330200 antigen exhibits a molecular weight of 22,000 amps that is approximately the same as the original HBc, in the C-terminal nucleic acid binding region with the HBc antigen, Specific monoclonal antibodies do not react. That is, the HBV nuclear-associated antigen can be regarded as an uncut pronuclear gene product (p22 antigen) of a message sequence depending on its molecular weight and does not contain a C-terminal nucleic acid binding region. The P22 antigen was separated by SDS-PAGE and excised from polyacrylamide gel. 'Material-assisted laser desorption freeing (MALDI) mass spectrometry (Carr et al.

Wiley & Sons,Inc” New York Units, 1997)確定胺基酸序列 ’即可明瞭p 2 2抗原係由記載於序列序號丨之丨7 8胺基酸所形 成之HBV蛋白。 以下雖稱呼該胺基酸序列經過確定之HBV核關連抗原 為HBV前核蛋白,惟本發明之HBV前核蛋白若與過去由 TAKAHASHI 等(Journal of Immunology, 147,3156-3160, 1991)所報告之hbv前核蛋白(前HBe抗原)相較,則缺乏N末 端(第一29號)之蛋胺酸,且第一28號之谷胺醯胺被乙醯化。 另,C末側於HBe抗原之C末的第149號之纈胺酸上結合著精 胺酸,至少存在到第150號。該HBV前核蛋白因為無法被辨 識HB V核酸結合部位當中含有SPRRR的部位之單株抗體 HB50所辨識,故有包含到第154號為止的胺基酸之可能性。 從本發明之HBV前核蛋白會形成不完全病毒粒子(類 病毒粒子)的現象,可以容易地推測出該蛋白形成蛋白鞘, 與HBc抗原競合而阻害病毒複製的情形。因此,本發明教 示使用HBV前核蛋白之HBV治療藥的可能性。 15 1330200 本發明之HBV前核蛋白係在HBV感染患者的體内形成 HBV類病毒粒子《另外’本發明亦教示該hbV前核蛋白存 在完全HBV病毒顆粒中的事實。亦即,HBV前核蛋白被認 為疋與HBc抗原一同形成HBV核蛋白勒(nucleo-capsid)。因 此’測定該HBV前核蛋白在做為肝炎和肝硬化病變或肝癌 之病態的診斷、標記上被認為是有用。 本發明之HBV前核蛋白與已知的HBe抗原、HBc抗原, 在功能和胺基酸序列上都不相同。然而,因為有功能上近似 的性質和胺基酸序列的重複,所以為了測定該HBV前核蛋白 ,與HBe抗原、HBc抗原先區分開來再做測定是必要的。但 是,如後述之實施例7所示,該HBV前核/核蛋白與HBc抗原 之量的比為12 : 1〜158 : 1,最低也有12倍以上的差距。 本發明之HBV前核蛋白與HBe抗原,或Takahashi等所 報告之具有訊息肽的HBe抗原不同,機能上前者形成類核 粒子(類病毒顆粒),相對地,後者係以游離狀態在血液中與 血清蛋白結合而存在。關於形成該類核粒子(類病毒顆粒) 之機能係該HBV前核蛋白與HBc抗原具有大致相同的機能 。從該HBV前核蛋白具有形成粒子的性質乙節,可以推測 其具有較之HBe抗原更接近HBc抗原的構造,胺基酸第一7 號之半胱胺酸與第61號之半胱胺酸之間的二硫化物結合並 未形成。 如後述之實施例9所示,根據HBV核關連抗原測定系統 ,以習知之HBc抗原測定法和HBe抗原測定法測定所檢測出 之HBV核關連抗原(HBV前核/核蛋白)時,冊成原和HBe 16 1330200 抗原未被檢出。這可以考慮成以下所示的情況。HBV核關 連抗原含有許多本發明之HBV前核蛋白。結合至習知所取 得之HBc抗原與HBe抗原的抗體有不結合至HBV前核蛋白者 ,HBV前核抗原之抗原性與HBc抗原和HBe抗原不同。 此情形顯示本發明之HBV前核蛋白幾乎無法在習知之 HBc抗原測定法和HBe抗原測定法中被檢出。亦即,可以視 為開始可以用木村等之HBV核關連抗原測定法來做測定。 HBV前核蛋白可以用HBV核關連抗原檢出。該測定系統之 特徵在於用界面活性劑處理含有HBV前核蛋白的檢體,並 在界面活性劑的存在下使其與抗體反應。因此,HBV前核 蛋白上之抗原決定部位在界面活性劑的存在下必須是安定 的。此外,抗體也必須使用在界面活性劑的存在下機能上 是安定的抗體。 辨識此種抗體之抗原決定部位以HBV核蛋白之第1 一 19、21 — 40、31-49、131 —140胺基酸的線性抗原決定體 ,以及第1一81的構造抗原決定體為適當。藉由將辨識此等 抗原決定部位的抗體加以組合,即可以測定HBV前核蛋白 。藉組合2個以上之此等辨識抗原決定部位的抗體可以檢出 HBV前核蛋白’特別合適之組合則是辨識第21 —4〇與31_ 49、第1—19與21 —40、第21 —40與31-49胺基酸的抗原決 定部位之抗體的組合;透過在此等組合中加入辨識其他抗 原決定部位的抗體,檢出感度會上昇。 在檢出時所使用的抗體必須是在界面活性劑的存在下 可以和上述抗原決定部位結合的抗體。在HBV前核蛋白測 17 1330200 定中所使用的界面活性劑以陰離子性界面活性劑為合適, 惟陰離子性界面活性劑與二離子性界面活性劑之組合,或 將陰離子性界面活性劑、二離子性界面活性劑及非離子性 界面活性劑組合在一起使用則感度會更為提高。在陰離子 性界面活性劑當中雖以SDS最為合適,惟其他陰離子性界 面活性劑也有效果,透過將SDS調換成其他構造類似的陰 離子性界面活性劑之方式’可以使HBV前核蛋白之上述抗 原決定部位露出,形成可以和抗體結合的狀態。 另外’關於本發明之HBV前核蛋白與習知之HBe抗原 、Takahashi等所報告之具有訊息肽的HBe抗原、HBc抗原之 胺基酸序列的差異點示於第1圖。HBV前核/核蛋白從本發 明可知其代表例係由第一28〜150的胺基酸序列所形成之 多肽。相對於此,HBe抗原係由第一 10〜149的胺基酸序列 ’具有訊息肽之HBe抗原係由第1〜183的胺基酸序列所構 成之多肽。 根據上述内容,先分離本發明之HBV前核蛋白與HBe 抗原、具有訊息肽之HBe抗原、HBc抗原,再進行測定之做 法雖然不容易,但是卻能利用是否可以形成該(類)病毒粒子 的機能和胺基酸序列的差異來加以分離。 首先,為了分離本發明之HBV前核蛋白與HBe抗原或 具有訊息肽之抗原,要利用該HBV前核蛋白係形成了HBV 類HBV顆粒,而HBe抗原或具有訊息肽之HBe抗原則是以游 離狀態(在本發明中,與抗體結合的HBe抗原也呈游離)存在 的特徵。實際上: 18 測〜(1)有一種將實施破壞病毒顆粒的處理之前所測定之 2值與實施過破壞病毒顆粒的處理後所測定之測定值加 所=的枝。也就是說,透過從實料破壞鱗顆粒後 ^的狀值,減去實施破壞病毒㈣之前所測定的測 值,是可以做測定的。 含(2)料,也有一種先分離(類)病毒顆粒再測定其中所 =咖前核蛋白的方法。在分離該(類)病毒顆粒的方法中 2一種例如以密度梯度離心將游離的抗原之分離部分和 >成(類)病毒難的分離部分分開來之方法,宜於測定含有 =病毒難的分離部分之HBV前核/核蛋白。除了以二密 '度離心分離游離的抗原與(類)病毒顆粒之方法以外,如 果&用特異地濃縮(類)病毒顆粒的方法,和特異的除去游離 的抗原的方法,則宜於分離後測定HBV前核/核蛋白的量。 、此種方法中之—種可舉例如利用抗HBS抗體之免疫沉 降法。利用抗HBs抗體進行免疫沉降時,藉測定沉降物中之 聊前核/核蛋白的方式,也可以特異地僅測定除去版 抗原的粒子狀HBV前核/核蛋白。 而,因為HBV前核蛋白與HBc抗原在形成(類)核粒子(( 類)病毒顆粒)的機能上相類似,所以為了進行分離測定可 以考慮使用對構成胺基酸序列不同的部分特異地結合(辨 識)之探針以將其分_方^也就是說,為了選擇^地測 定HBV前核蛋白,以使輯合至第―29〜〜職基酸之探 針為佳,為了選擇性地測定HBc抗原,則以使用結合至第 151〜183胺基酸的探針為佳。 1330200 另外,使用結合至雙方的探針,測定HBV前核蛋白+ HBc抗原之抗原量,然後再特異地測定任一者之抗原(蛋白) ,再經過減算,同樣也可以測定各個抗原(蛋白)的量。 實際上,在檢體中之HBV前核蛋白的測定中’必須進 行類病毒顆粒的破壞以使HBV前核蛋白露出之步驟。在該 步驟中係實施病毒之外套蛋白質’即HBs抗原之剝離’使用 讓HBV前核蛋白形成游離之處理劑。處理方法有鹼性處理 ,利用NaOH等之處理,HBs抗原被剝除,HBV内部的抗原 則形成游離。而其他的處理劑則可以使用界面活性劑,像 是Triton X-100和Nonidet P-40之類的非離子性界面活性劑 ’和SDS或肌胺酸鈉之類的陰離子性界面活性劑都是合適 的。此外,像是特許3171827號所申請之陰離子性界面活性 劑與其他界面活性劑的組合也是有效的。 若在不實施該類病毒顆粒之破壞、HBV前核蛋白之露 出步驟下’以辨識第—29〜149胺基酸的探針進行測定,就 會成為游離的HBe抗原或具有訊息肽之HBe抗原也受到測 定的情形。因此’在不實施游離的抗原和類病毒粒子之分 離下測定檢體中之抗原蛋白時,係以從經過利用界面活性 劑專之處理後的測定值’減去在未施以界面活性劑等之處 理下所剛定之HBe抗原的測定值所得之數值,做為粒子狀 HB V别核/核蛋白的測定值。 ^界面活性劑所導致之病毒顆粒的破壞、HBV前核蛋 各出(路呈)後’有利用辨識HBV前核蛋白的探 步驟。A > u步驟中,藉使用辨識第一 28~15〇胺基酸序列的 20 探針H蚊HBV前核蛋自。探針只要;I:結合至該前核 蛋白者皆宜’可以使用抗體、受體、引子、配位體等。 測疋法只要是利用HBV前核蛋白與探針的結合者皆可 代表性者有酵素抗體免疫法等。為將HBV前核蛋白與HBc 抗原刀離並測定,HBV前核蛋白以使用辨識—28--11的 探針,HBc抗原則以使用辨識151〜138的探針為佳。然而 透過以辨識共同區域1〜150的探針來測定HBV前核蛋白 和HBc抗原的合計量,再從合計量來做減算的方式也可 以將HBV前核蛋白加以定量。 實施例 以下實施例雖為例證本發明之例,惟本發明的範圍並 不因此而受到限制。 實施例1.

The amino acid sequence is determined to be a HBV pronuclear protein, but the HBV pronuclear protein of the present invention is the same as the hbv pronucleus previously reported by TAKAHASHI et al. (Journal of Immunology, 147, 3156-3160, 1991). Compared with the protein (pre-HBe antigen), it lacks the N-terminal (No. 29) methionine, and the first 28 glutamine amine is acetylated. In addition, the C terminal is at the end of the CBe antigen C. The 149th amino acid is bound to arginine, at least to No. 150. The HBV pronuclear protein is recognized by the monoclonal antibody HB50 which cannot be identified in the site containing the SPRRR in the HBV nucleic acid binding site. There is a possibility of containing an amino acid up to No. 154. From the HBV pronuclear protein of the present invention, incomplete virions (viral-like particles) are formed, and it is easy to infer that the protein forms a protein sheath, and HBc The situation in which antigens compete to prevent viral replication. The present invention teaches the possibility of using HBV prodrugs of HBV prodrugs. 15 1330200 The HBV pronuclear protein of the present invention forms HBV-like virions in the body of HBV-infected patients. [Additionally, the present invention also teaches the hbV pronuclei. The fact that the protein is present in the complete HBV virion. That is, the HBV pronuclear protein is thought to form the HBV nucleo-capsid together with the HBc antigen. Therefore, the HBV pronuclei protein is determined as hepatitis and cirrhosis. The diagnosis and labeling of pathological changes of lesions or liver cancer are considered to be useful. The HBV pronuclei protein of the present invention is different from the known HBe antigen and HBc antigen in terms of function and amino acid sequence. However, because of its function The approximate nature and the repeat of the amino acid sequence are necessary for the measurement of the HBV pronuclear protein, which is distinguished from the HBe antigen and the HBc antigen. However, as shown in Example 7 to be described later, the HBV is used. The ratio of the amount of pronuclear/nuclear protein to HBc antigen is 12: 1 to 158: 1, and the difference is also 12 times or more. The HBV pronuclei protein of the present invention and the HBe antigen, or the signal peptide reported by Takahashi et al. The HBe antigen is different, and the former forms a nucleus-like particle (viral-like particle). In contrast, the latter exists in a free state in combination with serum proteins in the blood. The function of forming such a nuclear particle (viral-like particle) is The HBV pronuclear protein has approximately the same function as the HBc antigen. The HBV pronuclear protein has the property of forming particles, and it can be speculated that it has a structure closer to the HBc antigen than the HBe antigen, and the amino acid No. 7 The disulfide bond between cysteine and cysteine 61 was not formed. As shown in Example 9 to be described later, according to the HBV nuclear-associated antigen assay system, when the detected HBV nuclear-associated antigen (HBV pronucleus/nuclear protein) is detected by the conventional HBc antigen assay and the HBe antigen assay, The original and HBe 16 1330200 antigens were not detected. This can be considered as the case shown below. The HBV nuclear associated antigen contains a number of HBV pronuclei proteins of the invention. The antibody which binds to the conventionally obtained HBc antigen and the HBe antigen does not bind to the HBV pronuclear protein, and the antigenicity of the HBV pronuclear antigen is different from that of the HBc antigen and the HBe antigen. This case shows that the HBV pronuclei of the present invention can hardly be detected in the conventional HBc antigen assay and HBe antigen assay. That is, it can be considered that the measurement can be carried out by using the HBV nuclear-associated antigen assay of Kimura et al. HBV pronuclei can be detected by HBV nuclear associated antigen. The assay system is characterized by treating a sample containing HBV pronuclear protein with a surfactant and reacting it with an antibody in the presence of a surfactant. Therefore, the epitope on the HBV pronuclear protein must be stable in the presence of the surfactant. In addition, antibodies must also be functionally stable in the presence of a surfactant. Identification of the epitope of such an antibody is based on the linear antigenic epitope of the first 19, 21-40, 31-49, 131-140 amino acid of HBV nucleoprotein, and the constructive antigenic determinant of the first 81 . HBV pronuclei can be assayed by combining antibodies that recognize these epitopes. By combining more than two of these antibodies that recognize the epitope, HBV pronuclei can be detected. A particularly suitable combination is the identification of 21st and 4th, 31st, 19th, 19th, 21st, and 21st. Combination of 40 and 31-49 amino acid epitopes; by adding antibodies recognizing other epitopes to these combinations, the sensitivity is increased. The antibody used at the time of detection must be an antibody which binds to the above-mentioned epitope in the presence of a surfactant. The surfactant used in the HBV pronuclear protein assay 17 1330200 is suitable as an anionic surfactant, but the combination of an anionic surfactant and a diionic surfactant, or an anionic surfactant, When combined with an ionic surfactant and a nonionic surfactant, the sensitivity is improved. Among the anionic surfactants, SDS is most suitable, but other anionic surfactants are also effective. By transposing SDS into other structurally similar anionic surfactants, the above antigenicity of HBV pronuclei can be determined. The site is exposed to form a state in which it can bind to the antibody. Further, the difference between the HBV pronuclei protein of the present invention and the conventional HBe antigen, the HBe antigen having the message peptide reported by Takahashi et al., and the amino acid sequence of the HBc antigen is shown in Fig. 1. HBV pronucleus/nuclear protein As is apparent from the present invention, a representative example is a polypeptide formed from the amino acid sequence of the first 28 to 150. On the other hand, the HBe antigen is a polypeptide composed of the amino acid sequence of the first to 183, and the amino acid sequence of the first 10 to 149 amino acid sequence. According to the above, it is not easy to isolate the HBV pronuclei protein and the HBe antigen of the present invention, the HBe antigen having the message peptide, and the HBc antigen, but it is possible to use whether or not the virion can be formed. The difference between the function and the amino acid sequence is separated. First, in order to isolate the HBV pronuclear protein of the present invention and the HBe antigen or the antigen having the message peptide, the HBV pronuclear protein system is used to form HBV-like HBV particles, and the HBe antigen or the HBe antigen having the message peptide is free. The state (in the present invention, the HBe antigen bound to the antibody is also free) is characteristic. Actually: 18 Measured ~ (1) There is a branch which is measured by the value of 2 measured before the treatment for destroying the virus particles and the measured value measured after the treatment for destroying the virus particles. That is to say, it is possible to measure by subtracting the measured value before the destruction of the virus (4) from the value of the scale after the scale is destroyed. Containing (2) material, there is also a method for separating the (viral) virus particles and then determining the pre-caffeine nucleoprotein. In the method of isolating the (type) virus particles, for example, a method of separating the separated portion of the free antigen and the separated portion of the virus into a difficult portion by density gradient centrifugation is suitable for determining that it is difficult to determine the virus. Part of the HBV pronucleus/nuclear protein was isolated. In addition to the method of centrifuging free antigen and (viral) virus particles by two-density, if & method for specifically concentrating (virtual) virus particles, and specific method for removing free antigen, it is suitable for separation The amount of HBV pronucleus/nuclear protein was then determined. Among these methods, for example, an immunosuppression method using an anti-HBS antibody can be mentioned. When immunoprecipitation is carried out using an anti-HBs antibody, it is also possible to specifically measure only the particulate HBV pronucleus/nuclear protein from which the plate antigen is removed by measuring the pre-transcriptional nuclear/nuclear protein in the sediment. However, since the HBV pronuclear protein and the HBc antigen are similar in the function of forming nuclear particles ((viral particles)), it is conceivable to specifically bind to a portion different from the constituent amino acid sequence for the separation measurement. (identifying) the probe to divide it into squares, that is, to determine the HBV pronuclear protein for selection, so that the probe to the ~29~~ acid group is preferred, in order to selectively When the HBc antigen is measured, it is preferred to use a probe which binds to the 151 to 183 amino acid. 1330200 In addition, the amount of antigen of HBV pronuclear protein + HBc antigen is measured using a probe that binds to both, and then the antigen (protein) of any one is specifically measured, and then subtracted, and each antigen (protein) can also be determined. The amount. In fact, in the measurement of HBV pronuclear protein in the sample, the step of destroying the viroid-like particle to expose the HBV pronuclear protein must be performed. In this step, the viral outer cover protein 'i.e., the peeling of the HBs antigen' is used to form a free treating agent for the HBV pronuclear protein. The treatment method is alkaline treatment, and the treatment of NaOH or the like, the HBs antigen is stripped, and the antigen inside HBV is free. Other treatments can use surfactants, such as nonionic surfactants such as Triton X-100 and Nonidet P-40, and anionic surfactants such as SDS or sodium sarcosinate. suitable. Further, a combination of an anionic surfactant as claimed in Japanese Patent No. 3,171, 827 and other surfactants is also effective. If the probe of the No. 29-149 amino acid is not detected by performing the destruction of the virus particle and the exposure of the HBV pronuclear protein, it will become a free HBe antigen or a HBe antigen having a message peptide. It is also subject to measurement. Therefore, when the antigenic protein in the sample is measured without separating the free antigen and the viroid-like particle, the surfactant is not subtracted from the measured value after the treatment with the surfactant. The value obtained by measuring the value of the HBe antigen immediately after the treatment is taken as the measured value of the particulate HBV nucleus/nuclear protein. ^ The destruction of viral particles caused by surfactants and the detection of HBV pronuclear proteins by HBV pre-nuclear eggs. A > u step, using the 20 probe H mosquito HBV pronucleus to identify the first 28~15 amino acid sequence. The probe may be any one of which: I: binds to the pronuclear protein, and antibodies, receptors, primers, ligands and the like can be used. As long as it is a combination of a HBV pronuclear protein and a probe, the test method can be represented by an enzyme antibody immunoassay. In order to isolate the HBV pronuclear protein from the HBc antigen, the HBV pronuclear protein is probed using the identification -28--11, and the HBc antigen is preferably the probe using the identification 151 to 138. However, the HBV pronuclear protein can also be quantified by measuring the total amount of HBV pronuclear protein and HBc antigen by using a probe that recognizes the common region of 1 to 150, and subtracting the total amount from the total amount. EXAMPLES The following examples are illustrative of the invention, but the scope of the invention is not limited thereby. Example 1.

(B) The re-separated fraction obtained by low-gradient sucrose density gradient centrifugation, 30%, 40%, 50% sucrose solution, 3.4 ml each from the high density 50% sucrose solution, carefully overlapping The layers were layered in a 12 ml centrifuge tube and allowed to stand at room temperature for 6 hours. The 24th and 25th peak separation portions of (A) were diluted twice with TE buffer [10 mM Tris-HCl (pH 8.0), ImM EDTA], and then laminated on the prepared sucrose density gradient solution. The Sw40Ti rotor (Beckman) was centrifuged at 33.4 Ki: pm for 15 hours at 4 ° C, and 300 separate portions were taken from the top to obtain 40 separated portions. Calculate the density of each fraction, and determine the HBV nuclear-associated antigen (PCT application: PCT/JP01/06947, Example 5), HBe antigen (PCT application: PCT/JP01/06947, Example 6), HBs antigen, HBV - In DNA PCR, the peak of the HBV nuclear-associated antigen appears at a lower density fraction than the peak of the HBV-DNA PCR, which contains the HBs antigen (Fig. 3). After peaking, each peak was stored at 4 °C. Example 2. Gel 遽 treated with NP-40 The peak fraction separated according to (A) of the above Example 1 (24-25) was buffered with 10 mM linalic acid containing 〇_l5M NaCl. When the liquid (pH 7.3) (PBS) was equilibrated with Superose 6 HR (Amersham) for gel filtration, the particles of HBV nuclear-associated antigen and HBc antigen were eluted 22 1330200 into the empty body fraction (Fig. 4) ). On the other hand, NP-40 was added to the peak separation portion (24-25) obtained by the separation of (A) of the above Example 1, so that the final concentration was 3%, and 37 ° C was used for stripping the HBs antigen.

The molecular weight separation portion of Superose 6 HR has a molecular weight of 40,000,000 or more, and these molecules are considered to have a viroid-like protein sheath particle structure. Example 3. The analysis obtained by the Western blot method and the method described in (A) of Example 1 were similarly treated with HBe antigen-positive serum to carry out sugarcane density gradient centrifugation, and 600 μl each was taken from the supernatant to obtain 20 Separate parts. SDS-PAGE was performed using this fraction and HBe antigen-positive serum, and after transfer to PVDF membrane (Immobilon, Milli-pore), the C-terminal nucleic acid binding of the monoclonal antibodies HB91 and HBc antigens of both HBc antigen and HBe antigen was identified. In the region, a Western blotting method using a specific monoclonal antibody HB50 was used to detect an HBV nuclear-associated antigen having a molecular weight of about 22,000 amps (Fig. 5). However, the fact that the HBV nuclear-associated antigen reacts to HB91 but does not react with HB50 becomes clear (Fig. 5, lower panel). The HB50 antibody is analyzed by the epitope, although it can be understood that it recognizes the 168-176 amino acid (5 (^?1^1^), in addition to its 141-159 amino acid (STLPETTVVRRRGRSPRRR) And the 150-167 amino acid (RRRGRSPRRRTPSPRRRR) is also reactive. The common sequence of these amino acids is SPRRR, and at least the sequence 23 1330200 is necessary in combination with the HB50 antibody. That is, since the 155th The SPRRR sequence is present, so the HBV pronucleus/nuclear protein of the present invention is considered to be a sequence lacking after 155. This fact can also be derived from the peak in the HBc antigen assay system using the HB50 antibody as a marker antibody alone. It does not overlap with the peak of the HBV pronucleus/nuclear protein (Fig. 2, Fig. 3). Example 4. Analysis of the amino acid sequence obtained by MALDI mass analysis will be based on the examples. The HBV nuclear-associated antigen isolation fraction obtained by the method of (A) was gelled using Superose 6 HR (Amersham) equilibrated with 10 Mm phosphate buffer (pH 7.3) (PBS) containing 0.15 M NaCl. When filtering, HBV nuclear-associated antigen and HBc antigen The formed particles were eluted into the hollow body separation portion. The hollow body fraction was laminated to TNE buffer containing 1% NP-40, 20% sucrose [10 mM Tris-HCl (pH 7.5), 150 mM NaCl, 1 mM On the EDTA], the particles containing the HBV nuclear-associated antigen particles were recovered by centrifugation for 15 hours at 33.4 Krpm and 4 ° C using a Sw40Ti rotor (Beckman). The particles were separated by SDS-PAGE and the HBV of 22 kDa was cut out. The region of the nuclear-associated antigen was subjected to MALDI-TOF mass analysis by Voyager-DE STR (Applied Biosystems) after trypsin digestion. As a result, sequences corresponding to sequence numbers 2, 3, 4, 5 and 6 were detected. 5 amino acids, wherein the terminal of the imidate of SEQ ID NO: 2 is acetylated. Example 5.

After removing the blocking solution, vacuum drying was performed. The serum 1〇〇μ1_addition treatment solution (15% SDS, 2% Tween 60) 50μb was treated at 70 ° C for 30 minutes, and 5 μμ1 was taken as the measurement sample. The reaction buffer was 1 μμ1. 5 μμ of the test sample was added to the above well, which was reacted at room temperature for 2 hours. After washing with a washing solution (0.05% Tween 20 '0.15Μ NaC Bu 10 mM acid natrate buffer (pH 7.4)) 0.4 ml, 'Alkaline Phosphotase (AP) labeled monoclonal antibody HB91 (identification site 1-19 amino acid) and HB110 (identification site 21-40 amino acid) were diluted to 〇.1μ§/ m b 0.5pg/m b and added to ΙΟΟμΙ/well to make it react at room temperature.

After washing 6 times with 0.4 ml of the washing solution, a CDP-Star with Emerald II (TROPIX) solution was added as a light-emitting substrate, and the mixture was allowed to react at room temperature for 20 minutes, and then the luminescence was measured. Example 6.

Example 7. Measurement of HBV pronuclear protein, HBe antigen, HBc antigen in the sample and calculation of the ratio The serum 7 sample was separated by sucrose density gradient centrifugation according to the method of the above Example 1 (A). In each sample, a separate fraction containing a low-density free HBe antigen (for example, in Figure 1, in the 1-19 separation portion 26, 1313030 minutes or so) and a separation portion containing a high-density virus particle (for example, The measurement of each antigen was carried out in the same manner as in Example 5 and Example 6 except that 'the 20th separated portion or more' was separated in Fig. 1 . When the low-density separated fraction was measured by the method of Example 5, the separated fraction was determined to be a free HBe antigen free of viral particles. When the high-density separated fraction was measured by the method of Example 5, since the measurement method was carried out by combining the HBc antigen and the particulate pronuclear protein, the value of Example 6 was subtracted from the value measured in Example 5. The value of the particulate HBV pronuclear protein can be calculated from the value. The ratio of HBe antigen, HBc antigen, and HBV pronuclear protein measured in this manner in each sample was calculated (Table 1). Table 1.

In all of the quantifiable examples, more than 90% of the HBc antigen is present in the high density separation fraction. The HBV pronucleus/nuclear protein present in the low-density fraction is HBe antigen; the HBV pronucleus/nuclear protein in the high-density fraction is the hbc antigen and the particulate HBV pronuclear protein. Therefore, the concentration of particulate pronuclear protein can be calculated by subtracting the HBc antigen concentration from the high-density HBV pronucleus/nucleus protein concentration. Example 8. Separate measurement of the free and particulate HBV pronucleus/nuclear protein and HBc antigen in the sample and the ratio of the HBV Direct-Mag Kit (JSR Corporation) "reaction buffer" 50μ1, "HBV supplement" The particles (anti-HBs antibody-phased magnetic gas particles) 5 〇 μ1, and the sample 200 μb were shaken at room temperature for 3 , minutes to bind the 28 1330200 HBV-related particles containing the HBs antigen. The magnetic particles are separated by a strong magnet, and the supernatant is removed. The supernatant contained free HBe antigen. 60% of a 15% SDS solution was added to the residual magnetic particles, and heated at 70 ° C for 10 minutes to dissolve the bound particulate HBV pronucleus/nuclear protein. The magnetic particles are separated by a strong magnet, and the extract is taken out. The HBV pronucleus/nuclear protein and HbcAg in the supernatant and the precipitated extract were measured by the methods of Example 5 and Example 6, respectively, and the HBe antigen, HBc antigen, and particulate HBV pronuclear protein in the sample were calculated. The respective concentrations and ratios. The results are shown in Table 3. In all of the quantifiable examples, more than 90% of the HBc antigen was present in the precipitate. That is, the particles coated with the HBs antigen are substantially all immunosuppressed. The HBV pronucleus/nuclear protein in the supernatant is HBe antigen, and the HBV pronucleus/nuclear protein in the sink is HBc antigen and particulate HBV pronuclei. Therefore, the concentration of particulate pronuclear protein can be calculated by subtracting the HBc antigen concentration from the pre-nuclear/nuclear protein concentration in the precipitate. The concentrations and ratios were very similar to those obtained by density gradient centrifugation of Example 7, and it was shown that both of these assays can be used for the determination of particulate pronuclei. Example 9: According to the difference in the morbid state of the particulate HBV pronuclear protein, in the same manner as in the case of the eighth embodiment, a total of 81 samples of the blood samples of the four tissues of the HBV-bearing hepatitis were measured. The free and particulate HBV pronucleus/nuclear protein, as well as the HBc antigen, were compared to the ratio of intact pronuclear/nuclear protein (antigen + HBc antigen + particulate HBV pronuclear protein) relative to the particulate HBV pronuclear protein. The results are shown in Figure 6. 29 1330200 In the case of HBe antigen-positive cases, 'the tendency to appear high in the case of acute hepatitis' tends to be low in cases of no symptomatic carriers and cirrhosis. In the case of the HBe antibody-positive case, the case of high incidence in chronic hepatitis and liver cancer tends to be low after acute hepatitis healing and in cirrhosis. Based on these results, a useful method for the diagnosis and treatment of hepatitis B can be obtained by measuring the particulate pronuclear protein, which can further be used in the pathological explanation of ΗB V and hepatitis B. Based on the knowledge thus obtained, it is also possible to obtain useful knowledge in the development of therapeutic drugs for hepatitis. Example 10 Comparison of Sample Processing Method In each sample pretreatment liquid, in the same manner as in Example 6, only the pretreatment liquid was changed, and the pretreatment of HBV positive serum 5 and the measurement of HBc antigen were performed. Compare the effects of each treatment method. Among them, SDS, N-Lauroyl sarcosin-Na, Deoxycholic Acid-Na are anionic surfactants, and n-Decyl trimethyl ammonium-Br is a cationic surfactant. The final concentration of the active agent in the sample treatment becomes one third of the pretreatment liquid, and the final concentration in the first reaction in the HBc antigen measurement system becomes 1 / 9.

Example 1 (A) The peak separation portion of the BV nuclear-associated antigen was treated with 1% NP-40 to remove the coat, diluted 10-fold (HBV nuclear-associated antigen content was about 150 ng/ml) and then subjected to the above determination. No HBc antigen was detected. Further, although the same sample was measured by the clinically used HBe antigen measuring system (Dainabot), the HBe antigen was not detected. Therefore, the particulate HBV pronuclear protein of the present invention is considered to have a different antigenicity from the HBc antigen and the HBe antigen. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic diagram showing the HBV pronuclear protein, the HBe antigen, the HBe antigen having a message sequence, and the amino acid range of the HBc antigen, and the morphology of each antigen in the blood. Fig. 2 is a schematic diagram showing the HBV antigen and HBV-DNA behavior of ΗB e antigen-positive serum separated by sucrose density gradient centrifugation. The HBV nuclear-associated antigen (black square), HBc antigen (#), HBs antigen (◊), HBe antigen (□), and HBV-DNA (〇) are shown in the respective fractions; the density of the separated fraction is indicated by a broken line. Fig. 3 is a schematic diagram showing the HBV antigen and HBV-DNA behavior when the separated fraction of the isolated HBV nuclear-associated antigen was separated by sucrose density gradient centrifugation by sucrose density gradient centrifugation at 32 1330200. The HBV nuclear-associated antigen (black square), HBc antigen (Φ), HBs antigen (◊), and HBV-DNA (〇) are shown in the respective fractions; the density of the separated fractions is indicated by a broken line. Figure 4 is a schematic representation of the behavior of gel filtration of HBV antigen. The above figure is the case where the largest separated fraction of the HBV nuclear-associated antigen separated by sucrose density gradient centrifugation is directly applied to the gel filtration without treatment. The figure below shows the same sample treated with 3 % N P - 40 and then filtered by gel. The amount of HBV nuclear-associated antigen (black square) and HBc antigen (φ) in each separated portion is shown. The dissolution position of the molecular weight marker is shown on the upper portion. Fig. 5 is an electrophoresis diagram showing the results of western blot analysis of HBe antigen-positive serum and its density gradient centrifugation section, in place of the photograph of the figure. The density gradient centrifugation sections 1 to 20 correspond to a sucrose concentration of 10 to 6 % 〇 Β Β 50 which is a monoclonal antibody which reacts only to HBc, and HB91 which reacts with both HBc antigen and HBe antigen. Figure 6 is a graphical representation of the ratio of total pronuclear/nuclear protein to the particulate pronuclear protein in each case. A positive example of HBe antigen is indicated by (Lu), and a positive example of HBe antibody is indicated by (〇).
