Description

1355418 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種細胞數量及細胞蛋白質量 測裝置與方法,尤指一種可對貼附或懸浮型細胞之 數量及特異蛋白質作非破壞性連續監測的裝置與 方法。 【先前技術】 φ 細胞行為的連續偵測: 有鑒於許多針對細胞的實驗及方法都將對細 胞造成傷害,因而無法對單一樣品做長時間的監 測,所以非破壞性、可以連續偵測細胞狀態的感測 方式或裝置非常有其必要,但卻不多見且仍有限 制。 1984年Giaever和Keese共同提出了一套稱為 細胞阻抗分析(Electrical Cell Impedance Spectroscopy, ECIS)的方法,利用電學的方式來測 量貼附型細胞之行為,並連續記錄細胞貼附電極介 ® 面所產生的電阻與電容抗。他們發現在使用金電極 材質或施加電場之下都對此種細胞沒有影響,細胞 無論在貼附、伸展、生長上都一直表現正常。此外, 在連續的量測紀錄中,總電阻值確實會隨貼附生長 的細胞而增加。 此類的測量方法上,阻抗分析必須以交流訊號 來做阻抗的量測,這是因為細胞膜如同電容器一般 有隔離直流耦合交流的特性,因此必須使用交流訊 號來對細胞進行量測。在許多傳統的細胞阻抗分析 中,多使用小於1 μ A的電流對細胞做量測,再藉 5 由量測待測電極兩端的微小電壓來做進一步分 析。因為其測量電路中的電流小於ΙμΑ,且所需的 測量時間極為短暫’在許多文獻中也表示此種測量 方式對細胞正常的生理並無影響,所以可視為一種 非破壞性的量測方式。 在研究的細胞種類中,細胞阻抗分析已經實際 應用在許多不同貼附型細胞數量的感測上,例如: 纖維母細胞(fibroblast)、上皮細胞(end〇thelial cell)、星狀細胞(astrocyte)、腎細胞(kidney cell)、 肝癌細胞、表皮性癌細胞等,這些細胞包括細胞株 (Cell line)及初級培養(Primary culture)細胞,但目 前為止仍無法對懸浮型細胞做數目的量測。 在電極設計上,傳統的細胞阻抗分析裝置多將 金電極設置在塑膠培養盤上,其中又分為一個微小 的偵測電極和一個較大的計數電極。研究發現如果 將此二電極改為兩個等大的電極,將會無法測量到 ^胞的變化。但另有學者使用鉑製作兩個等面積之 J ^電,(IDES),成功地連續偵測細胞貼附生長的 。這表示在細胞阻抗量測分析時,電極的形式 。對可測虽性有很大的影響。而近年來在類似 ,雖然有許多的研究嘗試利用不同的電極形 二=計來做細胞阻抗的量測,但從未有人提出對懸 g ^細胞數量偵測與細胞蛋白質偵測相關的解^ 大類現行測量細胞蛋白質方式約略可分為下列兩 1 ·破壞細胞型態的測量方法: 一般是將細胞溶解後做蛋白質的分離純化及 /里,或疋做蛋白質晶片的檢測,甚至藉由萃 取核糖^酸(RNA)來做分子生物的分析。常見的蛋 白質測量方法方法很多,例如做蛋白質膠片電泳 (SDS-PAGE)後以西方墨潰法(Western b〇〗t)比較蛋 白的表現量;又如高效液相層析(HPLC)後做分子 質譜(MS)分析;又如毛細管電泳(CE)後做免疫染色 (Immunostain)等等。這些方法需要破壞細胞,如果 需要做時間上的觀察,就需要準備許多不同時間點 的樣本’因此無法對樣本作連續非破壞的監測。 2.保留細胞型態的測量方法 一般以細胞免疫螢光染色 (Immunocytochemistry)為主,其是以帶有螢光物質 的抗體標示特定蛋白質。透過細胞免疫螢光染色, 觀祭者可以在螢光顯微鏡(Fluorescence microscope)下觀察蛋白質在細胞的位置,甚至以雷 射共輛焦顯微鏡(Confocal microscopy)觀察更清晰 的立體成像及動態變化。細胞免疫螢光染色雖然保 留了完整的型態,但細胞仍需移出培養箱,所以並 無法在顯微鏡下做長時間的觀察。此外,細胞免疫 螢光染色更具有操作時需要避光、螢光物質有其半 衰期、光學儀器昂貴等等的缺點。 蛋白質生物感測晶片之概況: 目前以電學方法進行量測蛋白質的感測晶片 主要為免疫晶片。關於免疫晶片,其主要是利用抗 原抗體特異性結合的原理而對蛋白質做量測,其方 法是將抗原蛋白塗佈在半導體表面,以測量其電容 特性的改變。研究結果發現當抗原抗體結合時,電 容的測量值將會下降。此外;也有在導電性高分子 表面接上抗體’以測量抗原抗體結合後導電性的變 化’研究也發現隨著待測抗原濃度的增加,導電度 的變化也越大。而這些檢測晶片的樣本皆需取自於 1355418 ϊΐ質fif液丄而樣本的準備如傳統的檢測方法 瓜,都品先將實驗細胞破壞,所以仍難以 樣本做連續性的測量。 早 職是之故,申請人鑑於習知技術中所產生缺 失,乃經悉心試驗與研究,並一本 ί置=本工r數量及細胞蛋白= 裝置與方法」,以下為本案之簡要說明。 【發明内容】 白質ϊίίΐΐίί提供一種細胞數量及細胞蛋 t Λ 藉由在目標細胞上通過一 =測,入帶導電金屬=== 裝置下對細胞特異蛋白質作非破壞性: ^ t ί i ^ 5^ 雷栖卜剎田々队x、<驟l括.(a)於一氧化銦錫 胞之-細胞蛋白質弟;該細 以性,-第以ϊΐ;ί= 過-:ί Ht子,:(c)於該氧化銦錫電極上通 i或ί ί該氧化銦錫電極之電阻抗 值或電容抗值換為—賴細胞蛋白質^見電量阻抗 雷托戶f述之方法’其中步驟(a)於該氧化銦锡 電極上同時培養—種以上之細胞。乳化銦錫 如上所述之方法,其中步驟(b)之該培養液包 8 1355418 a . 含複數種第一級抗體,該複數種第一級抗體分別可 與不同之細胞蛋白質特異性結合。 ' 如上所述之方法,其中步驟(b)加入分別可與 * 該複數種第一級抗體特異性結合的複數種第二級 •- 抗體,該複數種第二級抗體上均帶有金屬粒子。 . 如上所述之方法,其中步驟(c)之該電流每經 過一期間後通過該氧化銦錫電極。 為達上述目的,本案提供一種連續測量細胞蛋 白質表現的裝置,該裝置包含:一細胞;一細胞培 • 養液,用以提供該細胞生長,其中該培養液更包 含:一結合物,用以與該細胞之一細胞蛋白質特異 性結合,其中該結合物上帶有一金屬粒子,該金屬 粒子可於該結合物與該細胞蛋白質特異性結合 後,改變細胞的交流阻抗特性;一電極,與該培養 液電連接,用以提供該裝置之可感測性;及一交流 阻抗偵測裝置,與該電極電連接,用以偵測該電極 通過一電流時之一交流阻抗變化。 如上所述之裝置,其中該電極為由二線狀電極 所形成的一雙電極,該二線狀電極之個別線寬為 _ 0.4mm 〇 如上所述之裝置,其中該二線狀電極相互平 行,該二線狀電極之間距為4mm。 如上所述之裝置,其中該電極為一氧化銦錫電 極。 如上所述之裝置,其中該氧化銦錫電極位於一 絕緣基板上,其中該絕緣基板之材質為玻璃、石英 及塑膠其中之一或其組合。 如上所述之裝置,其中該結合物為一第一級抗 9 該第一級抗體特異性結合之-第二級抗 體之組合,該第二級抗體上帶有—金屬粒子。 子。如上所述之方法,其中該金屬粒子為一金粒 如上所述之裝置,其中該電極為一多樣本陣 賴触不同㈣料之樣本或同 日寸取付冋一樣本之複數組數據。 通過述之裝置’其中該電流每經過一期間後 細胞如上所述之方法’其中該細胞包含一種以上之 合物+胃培養液包含複數種結 生、,·σδ,且忒複數種結合物上均帶有金屬粒 -·^ί ί 之農置’其中該阻抗偵測裝置更包含 λ唬放大早凡,用以放大該阻抗變化。 方法為ίίϊ 本案提供-種連續細胞數目的 一細胞液;.⑷於一氧化銦錫電極上利用 試算表將該連續ί 值換為一連績細胞數目改變量。 mi ^ 時,其血為一懸浮型細胞 1355418 % . 如上所述之方法,其中步驟(b)之該電流每經 過一期間後通過該氧化銦錫電極。 ' 為達上述目的,本案提供一種連續測量細胞蛋 白質表現的裝置,該裝置包含:一細胞;一細胞培 •- 養液,用以提供該細胞生長;一電極,與該培養液 電連接,用以提供該裝置之可感測性;及一交流阻 ' 抗偵測裝置,與該電極電連接,用以偵測該電極通 過一電流時之一交流阻抗變化。 如上所述之裝置,其中該電極為由二線狀電極 φ 所形成的一雙電極,該二線狀電極之個別線寬為 0.4mm 〇 如上所述之裝置,其中該二線狀電極相互平 行,該二線狀電極之間距為4mm。 如上所述之裝置,其中該電極為一氧化銦錫電 極。 如上所述之裝置,其中該氧化銦錫電極位於一 絕緣基板上,其中該絕緣基板之材質為玻璃、石英 及塑膠其中之一或其組合。 φ 如上所述之裝置,其中該電極為一多樣本陣 歹|J,用以同時偵測複數個不同的實驗條件之樣本或 同時取得同一樣本之複數組數據。 如上所述之裝置,其中該電流每經過一期間後 通過該電極。 如上所述之裝置,其中該阻抗偵測裝置更包含 一訊號放大單元,用以放大該阻抗變化。 本發明經由上述構想的解說,即能看出所運用 之檢測裝置及其方法,確能對懸浮型或貼附型細胞 之數量及細胞蛋白質作非破壞性連續的測量。而為 11 1355418 了易於說明,本發明可藉由下述較佳實施例及圖示 以更加瞭解之。 【實施方式】 請參閱第一圖,其為本發明之一種不影響細胞 正常生長之氧化銦錫電極晶片。該氧化銦錫(ITO) 電極晶# 01包含氧化銦錫電極001、細胞培養區 002、一細胞培養間格003、一絕緣基板004及一 線路接觸片005。 此氧化銦錫電極晶片01,係在於絕緣基板004 上,製作出特殊規格的氧化銦錫電極001後,再透 過細胞培養間格003將氧化姻錫電極001間隔出細 胞培養區0 0 2。欲進行細胞或蛋白質檢測前’先將 細胞培養在細胞培養間格003中,而使細胞及其偵 測培養液105成為此感測電路的一部份。當細胞數 目或是細胞阻抗特性有變化時,則氧化銦錫電極 001之阻抗值亦可從線路接觸片005的輸出觀察出 變化。 因細胞本身為電的不良導體,而一般的細胞培 養液主要成分為離子溶液,故為良導體。在貼附型 細胞偵測時,細胞成為橋接兩端電極的電路,因此 細胞的變化即為電路的變化,並可在半導體氧化銦 錫電極裝置中可產生一阻抗特性,故而經由偵測整 體電路的阻抗特性可以測得細胞的行為。而在懸浮 型細胞培養環境中,細胞未與電極接觸,因此電流 會經由培養溶液連接電極兩端形成迴路而略過細 胞本身,因此這樣的操作無法偵測懸浮型細胞。因 此必須改變以純血清作為培養溶液,由於血清的電 阻較高,因此可驅使電流通過懸浮型細胞。藉由對 12 1355418 . 不同型態細胞處理以不同的培養溶液,使得懸浮型 或貼附型細胞在數目有變化時,可以從電阻抗值或 • 電容抗值中作連續觀察。 在細胞蛋白質的感測中,利用抗原抗體之原 •- 理,將會與標的蛋白質特異性結合之第一級抗體及 帶有導電金屬粒子且會與前述第一級抗體特異性 ' 結合之第二級抗體加入細胞培養液中共同培養。藉 由導電能力的差別(電阻係數:導電金屬粒子与 ΙΟ'6 Ωοιη ;

Description of the invention: [Technical field of the invention] The present invention relates to a device and method for measuring cell number and cell protein, in particular to a non-destructive continuous quantity of specific or specific proteins of attached or suspended cells. Devices and methods of monitoring. [Prior Art] Continuous detection of φ cell behavior: In view of the fact that many cell-based experiments and methods will cause damage to cells, it is impossible to monitor a single sample for a long time, so non-destructive, continuous detection of cell status The sensing method or device is very necessary, but it is rare and still limited. In 1984, Giaever and Keese jointly proposed a method called Electro-Electrical Cell Impedance Spectroscopy (ECIS), which uses electrical methods to measure the behavior of adherent cells and continuously records the cell attachment electrode surface. The resulting resistance and capacitance are resistant. They found that there was no effect on the cells under the use of gold electrode materials or the application of an electric field. Cells remained normal regardless of attachment, stretching, and growth. In addition, in continuous measurement records, the total resistance value does increase with the cells attached to the growth. In this type of measurement method, the impedance analysis must be measured by the AC signal. Because the cell membrane is like a capacitor, it has the characteristics of isolated DC-coupled AC. Therefore, the AC signal must be used to measure the cells. In many traditional cell impedance analyses, cells are measured using a current of less than 1 μA, and further analysis is performed by measuring the small voltage across the electrode to be tested. Because the current in the measurement circuit is less than ΙμΑ, and the required measurement time is extremely short'. In many literatures, this measurement method also has no effect on the normal physiology of cells, so it can be regarded as a non-destructive measurement method. Among the cell types studied, cell impedance analysis has been applied to the sensing of many different adherent cell numbers, such as: fibroblast, end〇thelial cell, astrocyte , kidney cells, liver cancer cells, epidermal cancer cells, etc. These cells include cell lines and primary culture cells, but the number of suspension cells has not been measured so far. In the electrode design, the conventional cell impedance analysis device mostly places the gold electrode on the plastic culture plate, which is further divided into a tiny detection electrode and a large counting electrode. The study found that if the two electrodes were changed to two equal-sized electrodes, the change in the cell could not be measured. However, another scholar used platinum to make two equal-area J ^ electricity, (IDES), and successfully detected cell attachment growth continuously. This represents the form of the electrode during cell impedance measurement analysis. It has a great influence on the measurability. In recent years, similarly, although many studies have attempted to measure cell impedance using different electrode shapes, there has never been a solution related to the detection of suspended g ^ cells and cell protein detection. The current methods for measuring cellular proteins in a large class can be roughly divided into the following two types: Measurement methods for destroying cell type: Generally, the cells are lysed and separated, and the protein is separated and purified, or the protein wafer is detected, or even by extracting ribose. Acid (RNA) to do molecular biology analysis. There are many common methods for measuring proteins, such as protein film electrophoresis (SDS-PAGE), and Western blotting (Western b〇 t) compares the amount of protein expression; and, after high performance liquid chromatography (HPLC), Mass spectrometry (MS) analysis; as well as immunostaining (Immunostain) after capillary electrophoresis (CE). These methods require disruption of the cells, and if time-consuming observations are required, samples of many different time points need to be prepared' so that continuous non-destructive monitoring of the samples is not possible. 2. Measurement method for retaining cell type Generally, immunocytotochemistry is used, which is a specific protein labeled with an antibody having a fluorescent substance. Through cellular immunofluorescence staining, the spectator can observe the position of the protein in the cell under a fluorescence microscope (Fluorescence microscope), and even observe clear stereoscopic imaging and dynamic changes with a Confocal microscopy microscope. Cellular immunofluorescence staining retains the intact form, but the cells still need to be removed from the incubator, so they cannot be observed under the microscope for a long time. In addition, cellular immunofluorescence staining has the disadvantage of requiring light protection during operation, half-life of the fluorescent material, and expensive optical instruments. Overview of Protein Biosensing Wafers: Sensing wafers that currently measure proteins electronically are primarily immunological wafers. Regarding immunochips, proteins are mainly measured by the principle of specific binding of anti-antigen antibodies by coating antigenic proteins on a semiconductor surface to measure changes in their capacitance characteristics. The study found that when antigen-antibody is combined, the measured capacitance will decrease. Further, there is also a case where the antibody is attached to the surface of the conductive polymer to measure the change in conductivity after antigen-antibody binding. The study also found that as the concentration of the antigen to be tested increases, the degree of change in conductivity increases. The samples of these test wafers need to be taken from the 1355418 enamel fif liquid helium and the sample preparation is like the traditional detection method. The product is destroyed first, so it is still difficult to measure the continuity of the sample. In the early years, the applicants were carefully tested and studied in view of the defects in the prior art, and a copy of the quantity and the cellular protein = device and method. The following is a brief description of the case.

The present invention, as explained above, shows that the detection device and method therefor can indeed perform non-destructive continuous measurement of the number of suspended or attached cells and cellular proteins. For ease of description, the present invention can be better understood by the following preferred embodiments and illustrations. [Embodiment] Please refer to the first figure, which is an indium tin oxide electrode wafer of the present invention which does not affect the normal growth of cells. The indium tin oxide (ITO) electrode crystal # 01 comprises an indium tin oxide electrode 001, a cell culture zone 002, a cell culture compartment 003, an insulating substrate 004, and a line contact sheet 005. The indium tin oxide electrode wafer 01 is formed on an insulating substrate 004, and a special specification of indium tin oxide electrode 001 is formed, and then the oxidized samarium electrode 001 is separated from the cell culture region 0 0 2 through the cell culture compartment 003. Prior to cell or protein detection, the cells are first cultured in cell culture compartment 003, and the cells and their detection broth 105 are part of the sensing circuit. When the number of cells or the impedance characteristics of the cells change, the impedance value of the indium tin oxide electrode 001 can also be observed from the output of the line contact piece 005. Since the cell itself is a poor conductor of electricity, and the general cell culture solution is mainly composed of an ionic solution, it is a good conductor. In the case of attached cell detection, the cell becomes a circuit that bridges the electrodes at both ends, so the change of the cell is a change of the circuit, and an impedance characteristic can be generated in the semiconductor indium tin oxide electrode device, so that the whole circuit is detected. The impedance characteristics measure the behavior of the cell. In the suspension cell culture environment, the cells are not in contact with the electrodes, so the current bypasses the cells by connecting the ends of the electrodes through the culture solution, so that the operation cannot detect the suspended cells. Therefore, it is necessary to change the pure serum as a culture solution, and since the resistance of the serum is high, the current can be driven through the suspension type cells. By treating different types of cells with different culture solutions, 12 1355418 can be continuously observed from the electrical impedance value or the capacitance resistance value when the number of suspended or attached cells changes. In the sensing of cellular proteins, the original antibody that specifically binds to the target protein and the first antibody with conductive metal particles and which are specifically associated with the aforementioned first-order antibody are utilized. Secondary antibodies are added to the cell culture medium for co-cultivation. By the difference in electrical conductivity (resistance coefficient: conductive metal particles and ΙΟ'6 Ωοιη; ΙΤΟ = 2χ10"4 Qcin ; Cell = 140 Ωοιη) > conductive metal particles are superior to indium tin oxide electrodes and fine cells, By the difference in conductivity between the indium tin oxide electrode, the conductive metal particles and the cells, the high sensitivity for detecting protein changes can be achieved, and the proteins to be detected can be continuously monitored. Please refer to the second figure, which is a schematic diagram of non-destructive continuous measurement of cell-specific proteins by passing through the indium tin oxide electrode 001 of the first figure.
