Abstract

The present invention discloses viral protein produced by an enterically transmitted non-A/non-B hepatitis virus factors. In a particular scheme, the protein and antibodies existing in an individual infected by the hepatitis virus factor have immunoreactivity. The protein can be used for a diagnostic method for detecting the infection of the enterically transmitted factor. The present invention also discloses DNA probes produced by the sequence of the virus factor, which can be used for identifying the complete virus factor, determining the sequence of the complete virus factor and detecting the existence of the virus factor in infected samples. The DNA probes are based on a specificity amplifying method of a DNA fragment derived form viruses.

Description

Prepare the method for protein produced by hepatitis virus factor
The application is the further part for 208, No. 997 U. S. applications submitted on June 17th, 1988, and this application is by the bibliography as this paper.
The present invention relates to recombinant protein, gene and gene probe, more specifically to this albumen and probe produced by Enterically transmitted non-A/non-B hepatitis viral agent, and relate to the use of diagnostic method and the vaccine application of these albumen and probe.
It has been reported that in Asia, Africa and the Indian subcontinent, intestinal transmitted property non-a, non-b type (ET-NANB) hepatitis virus factor is the cause of disease of many popular and fragmentary property hepatitis cases.Infection is acted on to be carried out typically by the water body of fecal pollution, but the virus can also be propagated by close physical contact.End poison seems that chronic infection can't be caused.Volunteer is infected by using the excrement isolate of collection, it was verified that the aetology of ET-NANB viruses;Immuno-electron microscope (IEM), which is studied, to be shown, a diameter of 27-34nm of the virion from infected individuals excrement.Virion can be pointed out with the serum antibody response from different geographic regions infected individuals, this phenomenon, and it is by caused by a kind of virokine or classification to have in the ET-NANB hepatitis of global range most of.In the individual serum by blood born NANB virus infection, antibody response is not observed, shows that there is different specificity between two kinds of NANB types.
In addition to serology difference, the infection of both NANB types also shows respective clinical significance.ET-NANB is characterized in acute infection, generally with heating and arthralgia, and portal inflammation, is also accompanied by the cholestasia (Arankalle) in liver biopsy.Symptom is general to disappear in six weeks.In contrast, blood born NANB is chronic infection in about 50% case.Heating and arthralgia are seldom observed, inflammation is then distributed mainly in parenchyma (Khuroo, 1980).Both virokines can also be distinguished according to the infectivity for primate host.ET-NANB can infect dog monkey (Cynomolgusmonkeys), but blood born sex factor can not.Blood born sex factor raw meat raw meat more black than ET-NANB more infectivities (Bradley, 1987).
In order to differentiate and clone the viral genome related to ET-NANB hepatitis sequentially, a large amount of effort have been made in the world.One of target of effort is to differentiate virus and its protein product and determine its feature, and this needs the genome orders of virus-specific.Another object is that production recombinant viral proteins, diagnosis and vaccine that it can be used in based on antibody.Although having made these effort, so far, do not identify the virus order related to ET-NANB hepatitis successfully also, do not differentiate yet or produce any virus specified proteins.

The professional in molecular genetics field it will be recognized that both the above order all discloses corresponding complementary DNA sequentially, and corresponding to shown two primary sequences and complementary DNA order RNA sequentially.In addition, wherein there is encoded peptide to translate frame, although do not list amino acid sequence clearly as in ET1.1 orders above, but this nucleotides still discloses effable peptide.I. define
Term defined below has following meaning:
" 1. intestinal transmitted property non-a, non-b type (ET-NANB) hepatitis virus factor " refers to a kind of virus, virus type or virus type, this factor (i) causes the catarrhal jaundice carried by water, (ii) dog monkey can be infected, (iii) there is different serological properties from hepatitis A virus (HAV) and hepatitis B (HAB), and (iv) inserts the homologous genome area of section comprising one with the 1.33kb cDNA in plasmid pTZ-KF1 (ET1.1), the plasmid is taken in preserving number as in CCTCC M89041 BB4 plants of colibacillus.
So-called 2. " homologous " refers to that nucleic acid fragment can hybridize the base mismatch pair that 25-30% is contained up in chain in phase mutual cross under hybridization conditions.If it is, in general, that (ibid, p.320-323) two single stranded nucleic acid molecules hybridize under conditions of described in Maniatis et al., then it is that homologous but used wash conditions are as follows to claim them:2 × SCC, 0.1%SDS, 2 times at room temperature, every time 10 minutes;Followed by 2 × SCC, 0.1%SDS, 50 DEG C next time, 30 minutes;Followed by 2 × SCC, 2 times at room temperature, every time 10 minutes.It is further preferred that homologous nucleic acid chains contain 15-25% base mismatch pair, 5-15% base mismatch pair is further more preferably comprised only.Stricter wash conditions can be used to be selected for these homologous degree, and be cloned with differentiating from gene library (or other inhereditary materials are originated), as is well known in the art.
3. if a DNA fragmentation is containing the base pair sequence identical or essentially identical with certain region of virokine genome, it is by ET-NANB virokines " generation " to claim this DNA fragmentation.
4. a protein if DNA or RNA fragments as being produced from ET-NANB virokines translate frame coded by, then it is by ET-NANB virokines " generation " to claim this protein.II. the ET-NANB fragments of clone are obtained
According to an aspect of the present invention, it was found that the DNA clone of virus-specific can be produced by following step, (a) RRNA is separated from the known bile with the ET-NANB dog monkeys infected, (b) cloned cDNA fragment to be to form frag-ment libraries, and (c) pass through and infection and non-infection bile source radioactive label cDNA resolution screening by hybridization library.A.cDNA fragment mixtures
Dog monkey is set to occur ET-NANB infection by being injected intravenously inoculation, inoculum is the suspension of 10%W/V Feces of Patients (27-34nm ET-NANB particle positives, average diameter 32nm).Infection animal is monitored by the rising of alanine aminotransferase levels, this rising shows to there occurs virus infection.According to disclosed method (Gravelle), confirmation ET-NANB infection is combined with the immunologic opsonin of viruslike particle (VLP) by seropositivity antibody.In brief, excrement (or bile) sample is taken by the animal after infecting 3-4 weeks, with phosphate buffer with 1: 10 dilution, this 10% suspension is clarified by low-speed centrifugal, continue through 1.2 and 0.45 microns of filter filtering.This material (Bradley) further can be purified by the precipitation process of 30% sucrose cushions.Obtained VLP preparations are mixed with dilute solution serum of the ET-NANB patients infected.After incubated overnight, make mixture centrifuged overnight to precipitate immune aggregation body, the antibody combined after dyeing with electron microscopic examination with VLP.
It can also confirm that ET-NANB infects by the seroconversion to VLP positive serums.In this method, the serum of infection animal is as described above with 27-34nm VLP mixing (this VLP in the fecal specimens of infected patient by separating), the antibody then combined by immunoelectronmicroscopy with VLP.
Bile can be intubated to collect bile fluid by following two ways by collecting in ET-NANB animals showing positives in bile pipeline, or in autopsy by bile pipeline in extraction.As described in example 1A, by hot phenol extraction by extracting total serum IgE in bile.Also according to described in example 1A, with this RNA fragment by triggering the corresponding double stranded cDNA fragment of synthesis at random.CDNA fragments are separated by gel electrophoresis or density gradient centrifugation, to obtain the fragment of required size, such as 500-4000 base pair fragments.
Although other viral material source production cDNA components, such as VLP obtained as fecal specimens (as described in example 4) can be used, but still preferably use bile source.According to an aspect of the present invention, by the card of immuno-electron microscope it has been found that the bile from ET-NANB infection monkeys has more complete virus particles than the material from fecal specimens.The bile obtained by the ET-NANB people infected or dog monkey can be used as ET-NANB virus proteins or genomic material or intact virus and source, and this bile constitutes the part of the present invention.B.cDNA libraries and its screening
Above-mentioned cDNA fragments are cloned into suitable cloning vector to form cDNA library.This can be completed by following step:Assemble suitable end manual splice for blunt fragment, such as EcoRI sequentially, then by the suitable insertion point of this fragment inserting clone carrier, such as single EcoRI sites.After preliminary clone, library can if desired cloned again, to improve the percentage of the carrier containing Insert Fragment.The building process in library is described in detail in example 1B.In this method, cDNA fragments is become blunt end, fit on EcoRI ends, and insert in bacteriophage lambda gt10 EcoRI sites.The Insert Fragment that this library phages is shown is less than 5%, after being isolated, Insert Fragment is cloned into again in λ gt10 carriers, produced bacteriophage contains more than 95% slotting section.
By the resolution hybridization with cDNA probes, screening is specific to ET-NANB order in cDNA library, and cDNA probes are produced by source infecting and being uninfected by.Carry out self-infection and be uninfected by bile or the cDNA fragments of faecal viruses isolate to be prepared as above.(Maniatis, page 109), is radiolabeled by random labelling, nick translation or end mark to fragment according to conventional methods.As example 2 is described in detail, hybridizes by being transferred to the nitrocellulose filter of duplication, and with the radiolabeled probe of infection genesis and non-infection genesis (control), above-mentioned cDNA library is screened.In order to reclaim the order for locating hybridization outside preferred 25-30% base mismatch is to scope, the clone hybridized under the conditions of Maniatis et al. (ibid, p.320-323) is described can be selected, but use following wash conditions:2 × SCC, 0.1%SDS, 2 times at room temperature, every time 30 minutes;Followed by 2 × SCC, 0.1% SDS, 1 time, 30 minutes at 50 DEG C;Followed by 2 × SCC, 2 times at room temperature, every time 10 minutes.By these conditions, Mexico's isolate can be differentiated by the use of ET1.1 orders as probe.Show that the plaque with the selective hybridization of probe of infection genesis preferably remakes flat board culture with low-density, and screened again as described above, to isolate the monospecific polyclonal for being specific to ET-NANB orders.As pointed by example 2, by these processes, 16 are identified and have occurred the clone of specific hybrid with the probe of infection genesis.One of them is named as λ gt10-1.1, and it contains 1.33kb Insert Fragment.C.ET-NANB is sequentially
Pass through the sequential determination of standard, it is determined that the base pair sequence for the ET-NANB fragments cloned in part B.In the illustrative method that example 3 is described, Insert Fragment is cut from the cloning vector of selection, is separated by gel electrophoresis, in the cloning vector for being inserted into the base pair sequence of known insertion point both sides.The specific carrier that example 3 is utilized is pTZ-KF1 carriers, and it is shown in Fig. 1 left side.By in the single EcoRI sites of the ET-NANB fragments insertion pTZ-KF1 plasmids from gt10-1.1 bacteriophages.As described in example 3, differentiate the recombinant of slotting section needed for carrying by the hybridization of the 1.33kb fragments with separating.A selected plasmid is accredited as pTZ-KFF1 (ET1.1), and this carrier produces expected 1.33kb fragments after being digested with EcoRI.BB4 plants of the colibacillus infected with pTZ-KF1 (ET1.1) plasmid have been deposited in American Type culture and have collected center (Rockville, MD), and preserving number is CCTCCM89041.
Fig. 1 bottoms give pTZ-KFF1 (ET1.1) schematic diagram of plasmid.The 5 ' of Insert Fragment and 3 ' end regions indicate A and C respectively, and intermediate region indicates B.Order in these regions is determined by the double deoxidation sequential determination (seeing below) of standard.Three short order (A.B and C) is from same insertion chain.It can be seen that B areas order is actually what is determined by opposition chain from example 3, therefore B Qu Shunxu given above represent the complementary order of institute's surveyor's chain.The base number of part order is general.
The later stage work in the present inventor laboratory identifies complete sequence (being also given above).The fragment of this complete sequence is easy to be prepared with restriction endonuclease.Computer analysis and identification is carried out to two kinds of orders of forward and reverse and goes out some cleavage sites.Following table summarizes these specific cleavage sites (forward sequence).Base number CC^WGG (BstNI) CCWGG 106,360,410,483 answered in discriminating order pairing order " forward direction " chain (^=cleavage sites),

According on the other hand, present invention additionally comprises the ET-NANB specific fragments or probe that can hybridize with ET-NANB genome orders or the cDNA being generated by it fragments.This fragment may include the cDNA fragments of the complete length as described in section II, or can be the shorter order by being produced in the cDNA fragments cloned.Will be it can be seen that by carrying out enzymatic digestion to complete length fragment under conditions of size fragment needed for producing, shorter fragment can be prepared from the description of iv section.Generated in addition, the order produced by cDNA fragments can also be used in these fragments by oligonucleotide synthesis method.The method or service for producing the oligonucleotide fragment of selecting sequence can be obtained.
In order to confirm that given ET-NANB fragments are strictly what is produced by ET-NANB virokines, the fragment can be made to hybridize with the electing property of cDNA from the source of infection.From descriptive purpose, in order to confirm that the 1.33kb fragments in pTZ-KF1 (ET1.1) plasmid are initiated by ET-NANB's, this fragment is cut from pTZ-KF1 (ET1.1) plasmid, purified, radioactive label is carried out by random labelling method.The cDNA for making labeled fragment and carrying out the separation of self-infection and the non-source of infection hybridizes, to confirm that cDNA of the probe only with the source of infection reacts.Example 4 illustrates the method, wherein, check above-mentioned radiolabeled 1.33kb fragments (coming from pTZ-KF1 (ET1.1) plasmid) and cDNA (being prepared by infection and the non-source of infection) combination.The source of infection includes the bile that (1) carrys out the freely dog monkey of a virus, the virus is produced by the known fecal specimens with the ET-NANB Burma patients infected, the virokine that (2) are produced by the fecal specimens of patient ET-NANB of Mexico.CDNA in every kind of fragment mixture, is expanded according to manual splice/primer extension method of example 4 first.The isolated fragment on Ago-Gel, then carries out Sowthern trace transfers, is then hybridized, and combines cDNA of the radiolabeled 1.33kb fragments with separating.As would be expected, the swimming lane containing source of infection cDNA shows fuzzy bonding probes band (cDNA expanded by manual splice/primer extension method is expected to wider a wide range of).Probe is not observed to be combined with the amplification cDNA from the non-source of infection.As a result show, 1.33kb probes are specific to the cDNA fragments related to ET-NANB infection.Had confirmed with ET1.1 as the similar research of probe, the probe can be with the ET-NANB sample hybridizations collected from Tashkent, Somalia, Borneo and Pakistan and other places.Secondly, the fact that probe is specific to the EAT-NANB associated orders from different continents (Asia, Africa and North America) illustrates, the African ET-NANB orders of clone are produced by universal type ET-NANB viruses or virus type, and it is responsible for worldwide ET-NANB virus infections.
In a related conclusive research, the probe that the genomic fragment with separating is combined is checked, these isolated fragments are by people or the preparation of dog monkey genomic DNA.Probe is not observed to be combined with any genomic fragment, this shows that ET-NANB fragments are not the endogenous fragment of people or dog monkey.
Another evidence that there is the specific orders of ET-NANB in these fragments is that the code area in fragment can express ET-NANB albumen.Following iv section discusses the method using these fragment expression albumen.
One important use of ET-NANB specific fragments is to differentiate the cDNA produced by ET-NANB, wherein containing other order information.Then, the cDNA newly differentiated produces new probe fragment again, enabling further repeated, until identifying complete viral genome and determining its order.The ET-NANB library other to differentiate and the method for being generated by it new probe, can typically follow clone and the system of selection described in section II.
These fragments (and the oligonucleotides prepared according to order given above) may further be used to the primer of the polymerase chain reaction (PCR) method as the ET-NANB viral genome materials in detection patient samples.Following V sections will describe this diagnostic method.IV.ET-NANB protein
As described above, by the way that the expression of frame code area can be translated in ET-NANB fragments, ET-NANB protein can be prepared.For the ET-NANB fragments of expressing protein produced by the cDNA cloned in a kind of method for optimizing, the cDNA makes the fragment that it produces required size, the preferably main random fragment between about 100 to about 300 base-pairs of size by processing.Example 5 is described digests the method for preparing this fragment by DNA.As it is desirable that obtaining the peptide antigen between about 30 to about 100 amino acid, digestion fragment preferably through excessive separation, for example, is separated by gel electrophoresis, to select the fragment in the range of about 100-300 base-pairs.A. expression vector
ET-NANB fragments are inserted in suitable expression vector.The example of one expression vector is λ gt11, and it contains single EcoRI insertion points at the base-pair of beta-galactosidase gene translation stop codon upstream 53.Therefore, insertion sequence will be used as beta galactosidase expressing fusion protein, it contains N-terminal portion, heterologous peptides and the C-terminal region with or without beta galactosidase peptide of beta-galactosidase gene (if heterologous peptides coded sequence is free of translation stop codon, C-terminal part will be expressed).This carrier also produces a responsive to temperature type repressor (c1857), it at the allowed temperature (such as 32 DEG C) cause the lysogenesis of virus, and cause virolysis if higher temperature (such as 42 DEG C).The advantage of this carrier includes:(1) high efficiency produces recombinant, and (2) can select the host cell of lysogenization, and (3) high level to produce the fusion protein of restructuring at a temperature of permission rather than non-permitted according to the growth of host cell.Further, since the beta galactosidase that the bacteriophage containing heterologous slotting section produces is inactivation, then the substrate reactions that the phagocytosis physical efficiency containing slotting section is easily dyed by beta galactosidase are differentiated.
In order to which the viral fragment digested is inserted in expression vector, if desired, it can be modified according to routine techniques, the manual splice for making it contain selectable restriction site, such as EcoRI manual splicies.Example 1 illustrates the method being cloned into digestion fragment in λ gt11, and this method comprises the following steps:Flat fragments end, is connected with EcoRI manual splicies, and fragment is imported in the λ gt11 that EcoRI is cut.The Viral genomic libraries of generation can be checked, to confirm to have generated relatively large (representative) library.For λ gt11 carriers, this can be completed by following methods:Suitable bacterial host is infected, flat board culture bacterium checks the plaque for losing betagalactosidase activity.Using the methods described of example 1, there is about 50% plaque to show and lose enzymatic activity.B. the expression of peptide antigen
The production of peptide antigen (being expressed in the form of fusion protein) is screened in the Viral genomic libraries of above-mentioned formation, the antigen has the immunocompetence with the antiserum reaction from ET-NANB seropositive individuals.In a preferred screening technique, the host cell that culture is infected with phage library carrier as described above duplicates culture plate, so that the recombinant protein antigen produced by cell is transferred on filter membrane with nitrocellulose filter.Then react filter membrane and ET-NANB antiserums, uncombined antibody removed by washing, then the anti-human antibody with mark reacts, the antibody with sandwich like way by anti-ET-NANB antibody bindings on filter membrane.
Generally, the bacteriophage plaque identified by the production of recombinant antigen interested, detects that they produce the situation of antibody response fusion protein again with relatively low density.By the method, the recombinant phage clone of some production immunocompetence recombinant antigens is identified.
In order to be purified into recombinant protein, production can be enlarged with the expression vector of selection.Production is enlarged using one kind in a large amount of known methods, these methods include:(a) suitable host (such as colibacillus) lysogenization is made with the λ gt11 recombinants of selection, (b) cultivates transducer cell, (c) purified recombinant antigens from dissolving cell under conditions of high-level heterologous peptides is produced.
In a method for optimizing of above-mentioned λ gt11 cloning vectors is related to, the high production strain of colibacillus host is infected with the library phages of selection, BNN103 plant, and carry out with two flat boards repeatedly culture.At 32 DEG C viral lysogenesis can occur at this temperature for one flat board culture, and another culture is at 42 DEG C, and the bacteriophage infected at this temperature is in dissolved state, and therefore prevents the growth of cell.It is therefore contemplated that the cell produced under relatively low rather than higher temperature is by successfully lysogenization.
Then, make to grow in lysogenization host cell liquid medium within, this condition is conducive to the high level production of the fusion protein containing viral slotting section, by quick-frozen dissolving cell with the fusion protein needed for discharging.C. the purifying of peptide
Differential precipitation, sieve chromatography, ion-exchange chromatography, isoelectric focusing, gel electrophoresis and affinity chromatography etc. can be may include by the method for purifying proteins purification of Recombinant peptide of standard, these methods.For fusion protein, such as the beta galactosidase fusion protein of above-mentioned preparation, the protein separation technology for purifying can be by the technological transformation for separating natural albumen.Therefore, for separation beta galactosidase fusion protein, it is easy to isolate albumen by simple affinity chromatography, even if cell dissolved matter is combined with the solid phase of beta galactosidase antibody just by surface.D. virus protein
The ET-NANB albumen of the present invention also can be produced directly by ET-NANB virokines.The VLP separated as described above by the fecal specimens of infected individuals, is a suitable virus protein material source.The VLP separated by fecal specimens can be further purified by affinity chromatography, then carry out Separation of Proteins (see below).Virokine can also be produced by group born of the same parents' culture, and this provides a convenient and potential concentrated source for virus protein.Have jointly 846 submitted on April 1st, 1986, No. 757 U.S. Patent applications describe a kind of three knurls (trioma) liver cell do not gone out, the NANB infection in its energy sertoli cell culture.Three oncocyte systems are to blend preparation to (being selected according to the stability of human chromosome) by making human liver cell be merged with mouse/people.Cell containing required NANB virokines, the human antibody using anti-ET-NANB is differentiated by immunofluorescence technique.
Before separation albumen, crush virokine by conventional method, these methods may include utilizing for sonication, high salt or low-salt conditions or detergent.
ET-NANB virus proteins can use the suitable solid phase that purifying ET-NANB antibody is combined according to standard method by affinitive layer purification.Antibody by affinitive layer purification, in this purifying, can also make the immunocompetence ET-NANB protein bindings of the restructuring of for example above-mentioned preparation in solid phase in itself, to separate ET-NANB antibody from immune serum.The antibody of combination is discharged from solid phase by standard method.
Another method is that ET-NANB antibody can be the monoclonal antibody (Mab) prepared according to following methods:With ET-NANB recombinant proteins immune mouse or other animals, make cell constantization, the successful fusion product of selection and the protein immunogen reaction of restructuring by separating lymphocyte in animal, and with suitable fusion partners.They can be used in above-mentioned affinity purification, to obtain natural ET-NANB antigens.V. practicality A. diagnostic methods
The particle and antigen of the present invention, and inhereditary material can be used to diagnose in detection method.The method of detection ET-NANB hepatitis includes, and analyzes biological sample such as blood sample, excrement or liver biopsy, and seeing whether there is has and ET-NANB hepatitis viruse analyte of interest.
Analyte can be the nucleotide sequence hybridized with probe, and the probe includes at least 16 continuous nucleotides in said sequence (cDNA is sequentially), typically 30 to 200 nucleotides, until the nucleotides of essentially completed order.Analyte can be RNA or cDNA.Typical analyte is to suspect the virion for ET-NANB, or a kind of particle that this classification is just being excluded for it.Virion further feature is that have a rna virus cdna group, the order that the genome contains has at least about 80% homologous degree with the order of at least 12 continuous nucleotides in above-mentioned " forward direction " and " reverse " order, typically there is at least about 90% homologous degree with least about 60 continuous nucleotides in the order, and one and the order of complete length homologous order substantially can be contained.In order to test and analyze thing, in the case of analyte and probe hybridization, the probe can contain detectable mark.
Analyte, which may also comprise, recognizes a kind of antibody of antigen, such as cell surface antigen in ET-NANB virion.Analyte can also be ET-NANB viral antigens.When analyte is antibody or antigen, immune complex can be combined to form with the antigen or antibody and analyte of mark respectively, then can detect this compound by marking.
It is, in general, that the method for detection and analysis such as surface antigen and/or complete particle is to be detected as basis with immune.Immunodetection can be used to determine the antibody produced in host due to the infection of ET-NANB hepatitis viruses, or directly determine virion or antigen.This technology is it is well known that without being described in detail here.The example includes heterogeneous and homogeneity immunoassay technology.Both technologies are all based on forming immune complex between virion or its antigen and corresponding specific antibody.The heterogeneous detection method of viral antigen is usually using the specific monoclonal or polyclonal antibody combined with solid phase surface.Sandwich assay is just becoming more prevalent.Homogeneous detection method can also be used, this is carried out in the solution without solid phase, for example, determine due to the enzyme activity difference that free antibodies is combined and produced with enzyme-antigen conjugates.Some suitable detection methods are disclosed in US3,817,837,4,006,360,3,996,345.
When determining the antibody by ET-NANB virus inductions, detection IgG or IgM antibody can be removed as specific binding agents with the virus and antigen of the present invention.Because IgM antibody is usually the antibody that occurs first in course of infection, now IgG synthesis may be also not actuated, therefore, by specifically differentiating IgM and IgG antibody in host blood, actually or with regard to doctor or other researchers can be made to determine that the infection is recent chronic.
In a kind of diagnostic method, test sera is set to be combined with the surface the former solid-phase reagent reaction of ET-NANB proteantigens.After anti-ET-NANB antibody is combined with reagent, uncombined serum component is washed away, the anti-human antibody of the reagent and mark is reacted, display thing is combined on reagent, binding capacity is proportional to the ET-NANB amount of antibody combined in solid phase.Washing reagent determines the amount of the display thing combined with reagent to remove uncombined labelled antibody.It is, in general, that the display thing is a kind of enzyme, it is detected by making solid phase be incubated with suitable fluorescence or chromogenic substrate.
Solid phase surface reagent in above-mentioned detection method is prepared by known technology, for making protein substance adhere to solid support, such as polymeric beads, leaching label or filter.These adherence methods generally comprise the non-specific adsorption of protein and solid phase, or protein and solid phase covalent bond, reacted generally by the chemical active radical on free amino and solid phase, carboxyl base, hydroxyl or the aldehyde radical of such as activation.
In second of diagnostic method, i.e., so-called homogeneous detection method produces some changes with the antibody of solid phase binding in response matrix, and these changes can be detected directly in matrix.So far, it is known that the general type of the homogeneous detection method proposed has:(a) (Spin-labeled) of spin labeling shows thing, detected with the antibody of antigen binding by shown mobility (broadening at spin-spin splitting peak), (b) fluorescence display thing, surveyed and combined by the change detection of fluorescence efficiency, (c) enzyme shows thing, antibody binding influences the interaction of enzyme/substrate, and the display thing that (d) liposome is combined, with reference to causing liposome dissolving and discharge Nang Bao display thing.These methods follow the conventional method progress for preparing homogeneous detection reagent with the adaptation of proteantigen of the present invention.
In each above-mentioned detection method, it is directed to make the serum of test individual react with proteantigen and check antigen, sees with the presence or absence of the antibody for having combination.In the detection of first method, it may include make the anti-human antibody of mark and antibody binding to be checked, check that antibody is IgM (acute stage) or IgG (convalescence), and determine with because of the display thing quantity being combined.In the detection of second method, it may include observe the effect after antibody is combined with homogeneous detection reagent.
Detecting system or medicine box for carrying out above-mentioned detection method also constitute an aspect of of the present present invention.Medicine box generally includes the solid phase that surface is combined with recombinant protein antigen, the antigen is that (a) has the immunocompetence for being directed to the antibody being present in intestinal transmitted property non-a, non-b type virokine capsule sense individual, and (b) is produced from the virus hepatitis factor, the genome of the factor contains one and inserts the homologous region of section with plasmid pTZ-KF1 (ET1.1) 1.33kb DNA EcoRI, and the plasmid is taken in preserving number as in CCTCCM89041 BB4 plants of colibacillus.It is used to detect the anti-ET-NANB antibody of surface combination in medicine box by the anti-human antibody of display substance markers.B. the application of viral genome diagnosis
The inhereditary material of the present invention can be used in a variety of detection methods in itself, using the probe as the inhereditary material in natural infect.A kind of method for making nucleic acid target amplification (for then being analyzed by hybridization check) is so-called polymerase chain reaction (PCR) method or round pcr.Using the Oligonucleolide primers opened each other and based on above-mentioned genetic sequence, round pcr can be used for detecting the virion of the present invention in suspected pathological sample.Primers complementary is in the opposition chain of double chain DNA molecule, and they are typically separated by about 50-450 or more nucleotides (being typically no more than 2000 nucleotides).The method includes preparing special Oligonucleolide primers, then repeats following circulations:Target DNA is denatured, and primer is combined, and is extended to obtain the DNA fragmentation of the length according to desired by primer interval with archaeal dna polymerase.The extension products produced by a primer are used as the extra target sequence of other primer.The amplification degree of target sequence is controlled by cycle-index, and by simple formula 2nMake theoretical calculation, wherein n is cycle-index.Assuming that the average efficiency circulated every time is about 65% to 85%, then 25 circulations produce the target sequence that 0.3-4.8 million is copied.PCR method is recorded in many publications, including Saiki et al., Science230:1350-1354,1985;Saiki et al., Nature 324:163-166,1986;Scharf et al., Science 233:1076-1078,1986.Referring also to US 4,683,194;4,683,195;4,683,202.
The present invention includes the specific diagnostic assays of a measure ET-NANB virokine, and the method is based on the selective amplification of ET-NANB fragments.The method utilizes a pair of single-stranded primers, they are produced by the non-homogeneous area of DNA double chain fragment opposition chain, the double-stranded DNA is produced by intestinal transmitted property hepatitis virus factor, the genome of this factor contains one and inserts the homologous region of section with the EcoRI of 1.33kb DNA in plasmid pTZ-KF1 (ETI.1), and the plasmid is taken in preserving number as in M89041 BB4 plants of colibacillus.These " primer segments " constitute an aspect of of the present present invention, and they are prepared by ET-NANB fragments above for example described in section iii.This method is as described above, it then follows US4, the method for the nucleic acid sequences for expanding selection disclosed in 683,202.C. peptide vaccine
Any antigen of the present invention can be used in preparing vaccine.Prepare the fixed particle antigen by being separated in bile of preferred initial substance of vaccine.Antigen is preferably reclaimed first in the form of complete particle as described above.However, it is also possible to by preparing suitable vaccine from the particle or non-particle recombinant antigen of other source separation.If using non-particle antigen (being usually soluble antigen), preferably using and preparing vaccine by the albumen of virus envelope or viral capsid generation.These albumen can pass through above-mentioned affinitive layer purification.
If purifying protein does not possess immunogenicity in itself, it can be incorporated on carrier so that albumen has immunogenicity.Carrier includes bovine serum albumin, keyhole limpet hemocyanin etc..Preferably make antigen purification extremely substantially free of people's albumen, but this is not required in that.But importantly, in antigen can not the albumen containing nonhuman origin, virus and other materials, they may be imported by various pollution channels, for example, cultivate or obtain nutrient matrix used by virus, cell line, the pollution of tissue or pathology liquid.
Inoculation can be carried out by conventional methods.For example, antigen (either virion or albumen) can be used in suitable diluent, such as water, physiological saline, buffer solution, complete or incomplete adjuvant.Immunogene is applied with induction of antibodies using standard technique, such as containing inactivation or the virion weakened or the hypodermic injection of the physiological compatibility sterile solution of antigen.The virion of immune response amount typically can be produced by vaccinal injection administration, volume is generally 1 milliliter or less.
One specific vaccine combination example includes a kind of pharmaceutically acceptable adjuvant, a kind of recombinant protein or protein mixture produced by Enterically transmitted non-A/non-B hepatitis viral agent, the genome of the factor contains one and inserts the homologous region of section with the EcoRI of 1.33kbDNA in plasmid pTZ-KF1 (ET1.1), and the plasmid is taken in preserving number as in M89041 BB4 plants of colibacillus.Vaccine is applied with the interval of determination, until detecting significant ET-NANB antibody titers in serum.This vaccine will prevent ET-NANB infection.D. antibody and antiserum are prevented and treated
In addition to as vaccine, composition can also be used for preparing the antibody for ET-NANB virion.Antibody can be used directly as antivirotic.In order to prepare antibody, host animal is immunized using virion, or if appropriate, the non-particle antigen for making virion naturally-produced as described above combined with carrier and as vaccine.Human serum or blood plasma are collected after suitable time interval, to provide the composition containing the antibody that can be reacted with virion.By using (such as) saturated ammonium sulfate or DEAE Sephadex, or other technologies known in the art, gamma Globulin component or IgG antibody can be obtained.Antibody will not substantially produce many unfavorable side effects, and this side effect may be combined with other antivirotics such as medicine.
Minimized by making potential unfavorable immune system response, antibody compositions can be made to become that there is bigger compatibility with host system.This is completed by following methods:All part Fc parts of the antibody of alien species are removed, or use the antibody of the same race with host, such as using the antibody from the miscellaneous knurl of people/people.
Antibody may further be used to the means as enhancing immune response, because antibody-viral compound is recognized by macrophage.The amount of application of antibody can be similar to the antibody amount of application for other treatment.For example, other viral diseases such as rabies, measles and hepatitis B infection in early days, the amount of application of the gamma Globulin of collection is weighed oneself for 0.02-0.1ml/, with the entrance cell of viral interference.Accordingly, it is capable to which the antibody reacted with ET-NANB virion, can be combined the host being passively applied to infected with ET-NANB viruses, to strengthen the effect of immune response and/or antiviral drugs individually or with another antivirotic.
In addition, the antibody of anti-ET-NANB viruses can be induced as the anti-id AB of immunogene by applying.The convenient practice is that anti-id AB is induced in host animal using the ET-NANB antiviral antibody preparations for the purifying being prepared as above.Composition is administered to host animal in suitable diluent.After administration, the administration typically repeated, host produces anti-id AB.In order to eliminate the immunogenic response for being directed to Fc areas, the antibody by being produced in the animal of the same race with host animal can be used, or remove the Fc areas of institute's administration of antibodies.Induced in host animal after anti-id AB, take out serum or blood plasma to provide antibody compositions.Can be as above in face of purified composition described in the anti-ET-NANB antiviral antibodies of purifying, or by using the affinitive layer purification for the anti-ET-NANB antiviral antibodies for being incorporated into affinity substrate.The conformation of produced anti-id AB is similar to real ET-NANB antigens, and can be used to prepare ET-NANB vaccines, and without using ET-NANB particle antigens.
If being used as inducing the means of anti-ET-NANB antiviral antibodies in patient body, the mode of injection of antibodies is identical during purpose with for being inoculated with, i.e. in the diluent of PHYSIOLOGICALLY COMPATIBLE, under conditions of adjuvant is with or without, muscle, intraperitoneal, hypodermic injection etc. are carried out with valid density.One or many booster shots are probably needs.The method that ET-NANB antiviral antibodies are induced with anti-idiotype, can slow down may be by passively applying the problem of anti-ET-NANB antiviral antibodies cause, such as unfavorable immune response, and blood constitutent to applying purifying it is related the problem of, such as by also undiscovered viral infection at present.
