The present invention relates to adult T-cell leukemia (ADULT).
T-CELL LEUKEMIA, hereinafter referred to as "ATL")
A novel antigenic protein (ATL-associated antigen, hereinafter referred to as "ATLA") that specifically reacts with the serum of ATL patients is immobilized on an insoluble support. The present invention relates to a new method for easily and rapidly measuring the above-mentioned ATLA antibody by fluorescence or enzyme immunoassay using insolubilized antigen. ATL is a malignant disease that affects adults.
At present, the etiology is still unknown [Takatsuki, K. Uchiyama, T., Saqawa, K.
and Yodoi, J., (1977) in Topics in
Hematoloay,, eds.Seno, S., Takaku, F.,
and Irino, S. (Excepta Medica,
Amsterdam), pp73-77 and Uchiyama, T.,
Yodoi, J., Saqawa, K., Takatsuki, K. and
See Uchino, H., Blood 50, 481-492 (1977), etc.]. In recent years, a measurement technology using fluorescence immunoassay for ATLA antibodies has been proposed, which enables the diagnosis of ATL mentioned above [Proc. Natl. Acad. Sci. USA., Vol. 78, No. 10,
p6476−6480 (1981)]. In this method, cultured ATL cells themselves are used as an antigen, placed on a glass slide, and reacted with the test serum and fluorescently labeled anti-human immunoglobulin G antibody on the slide. The purpose was to observe and measure the localization of labeled substances. However, the above method requires the use of living cells themselves as antigens and the observation under a microscope for each sample (test serum), which of course requires frequent operations.
The drawback was that a large number of specimens could not be easily and quickly measured and diagnosed. In addition, if the measurement method is to be widely disseminated, it will be necessary to be able to carry out the measurement under certain conditions, but the method proposed above is based on the use of living cells themselves, and the antigen positivity rate will fluctuate. However, it was difficult to consistently obtain a certain antigen in a stable manner, which could lead to errors in measurement and diagnosis. The present invention provides a new method for measuring ATLA antibodies that eliminates all the problems found in the above-mentioned methods for measuring ATLA antibodies. That is, the present invention provides a fluorescence or enzyme immunoassay characterized in that it uses an insolubilized antigen obtained by immobilizing at least one selected from soluble cytoplasmic proteins of ATL cells and solubilized proteins of ATL viruses on an insoluble support. This relates to a method for measuring ATLA antibodies using the method. As a result of intensive research, the present inventors found that culture
We discovered that the soluble cytoplasmic protein of ATL cells (hereinafter referred to as "SCP") and the solubilized protein of ATL virus (hereinafter referred to as "VAP") can serve as antigens that specifically react with ATLA antibodies. It has been found that when an insoluble antigen immobilized on a support is used, a large amount of specimen can be measured easily, quickly, and always under constant conditions with high accuracy.
The present invention was completed based on this new knowledge. According to the method of the present invention, a large amount of specimen can be processed quickly with a simple operation, for example, compared to the above-mentioned conventional method under a microscope.
The amount and speed can be measured more than twice as much. Culture used as raw material for SCP in the present invention
ATL cells have already been established as cell lines [Miyoshi, I., Kubonishi, I.,
Sumida, M., Hiraki, S., Tsubuta, T.,
Kimura, I., Miyamoto, K. and Sato, J.,
Gann 71, 155-156 (1980)], as well as ATL isolated from peripheral blood or lymph nodes of ATL patients using conventional methods.
Cell culture cells and the above ATL cells were separately cultured with human T cells.
Cultured cells obtained by mixed culture with cells [e.g.
Nature, 294 , 770-771 (1981)]. There are no particular restrictions on the human T cells used in the above mixed culture, such as peripheral blood, bone marrow,
Examples include various T cells derived from lymph nodes, spleen, tonsils, thymus, etc. Further, the above-mentioned culture of ATL cells and mixed culture of the ATL cells and human cells can be carried out by conventional methods. As the medium, any of the various nutrient media commonly used for cell culture can be used. Preferred media include, for example, RPMI 1640 medium (Flow Laboratories
Examples include a medium obtained by modifying Eagle's minimum essential medium (MEM medium) using a serum supplement such as fetal calf serum (FCS) or calf serum. The culture conditions are not particularly different from those used for normal cell culture, and generally include a temperature of approximately 36-38°C.
A pH of 6.4 to 7.6 can be adopted. In addition, the above medium contains T.
Various drugs known as growth promoters such as cell growth factor (TCGF) or inducers of mammalian retroviruses, such as 5-iodo-2'-deoxyuridine (IdUrd), cycloheximide (CH), and puromycin. ), phorbol 12-myristate 13-acetate (TPA), n-butyrate (n-sodium acetate), etc. can be added and used as appropriate. Cultivation is usually advantageously carried out by exchanging the liquid every 3 to 5 days, thereby allowing the desired cells to proliferate well. Further, the SCP can be obtained by homogenizing the cultured ATL cells in an appropriate buffer such as physiological saline or phosphate buffered saline, and then collecting the supernatant by an appropriate means such as centrifugation. Used as a raw material for VAP in the present invention
Examples of the ATL virus include those isolated from the above-mentioned ATL cell culture solution by conventional methods. The above-mentioned separation of the ATL virus is carried out by a conventional centrifugation method, etc., and in the present invention, it is particularly preferable to use an ATL virus that has been further purified by a density gradient method or the like. VAP is ATL above
It can be obtained by solubilizing the virus. The solubilization can be easily carried out using conventional solubilizing agents. Various surfactants can be used as solubilizers, such as "Triton X-100" (manufactured by Wako Pure Chemical Industries, Ltd.) and "NP-40".
(manufactured by Ciel Corporation), nonionic surfactants such as dichitonin and urea, and anionic surfactants such as sodium dodecyl sulfate (SDS). There are no particular restrictions on the solubilization method, but it is more preferable to use a solubilizing agent of 0.01% to the critical micelle forming point and to take several minutes to 6 hours at a temperature of about 0 to 100°C. It is done. The VAP thus obtained
is preferably further purified according to conventional methods such as centrifugation, diafiltration, etc., and further purified by e.g. DEAE
- It is preferable to apply it to an anion exchange column such as cellulose, DEAE-Sephadex, etc., to adsorb and remove remaining viral nucleic acids. The insolubilized antigen used in the present invention is produced by immobilizing the above-mentioned SCP and/or VAP on an insoluble support. There are no particular restrictions on the insoluble support used, and examples include common supports commonly used in physical adsorption methods, specifically porous supports such as polystyrene, glass, polycarbonate, and polypropylene. Immobilization of SCP and/or VAP on such an insoluble support can be
This can be done according to conventional methods. For example, place the insoluble support and SCP and/or VAP in various solutions such as physiological saline and phosphate buffer, and
The reaction may take about 2 to 24 hours at a temperature of about .degree. The above reaction is preferably carried out under reduced pressure conditions. After completion of the reaction, adsorption sites remaining on the insoluble support used are saturated using, for example, 0.2% gelatin, 0.2% maggot serum albumin (BSA), etc., according to a conventional method. The insoluble antigen thus obtained is washed with water and then stored in a dry state or in the above buffer. The method of the present invention is carried out by measuring the labeling activity of a labeled antigen-antibody complex using the insoluble antigen obtained as described above according to a conventional fluorescence or enzyme immunoassay method. More specifically,
A test serum diluted as necessary is added to the insoluble antigen to cause an immunoreaction, and after washing, the resulting antigen-antibody reaction product is labeled by reacting with a labeling agent, and the labeled complex is The labeling activity of the body is measured according to a conventional method. In particular, according to the present invention, by using the above-mentioned insoluble antigen, a large amount of test serum can be measured easily, quickly, and accurately at one time under certain conditions. In the above, the test serum is, for example,
Serum separated from blood collected in a conventional manner from a subject whose ATLA antibody is desired to be measured, or serum diluted with an appropriate buffer can be used. The buffer used here is not particularly limited, but it is usually appropriate to use a weak phosphate solution (PH7.4).
In addition, the immune reaction between the test serum and the insoluble antigen is as follows:
This can be done simply by mixing and contacting the two. The reaction is usually completed in about 0.5 to 16 hours at a temperature of about 4 to 37°C, and after the reaction is completed, the reaction is thoroughly washed with an appropriate buffer, preferably physiological saline or the buffer used to dilute the test serum. is desirable. Following the above reaction, labeling of the resulting antigen-antibody reaction product with a labeling agent is carried out by mixing a labeling agent pre-diluted with the same buffer as above with the antigen-antibody reaction product for approximately 4 to 4 hours. The reaction is carried out at 37° C. for about 0.5 to 16 hours, and after the reaction is completed, it is desirable to thoroughly wash the composite obtained in the same manner as above. As the labeling agent in the above, any conjugate of a substance capable of specifically binding to an antibody and various enzyme labeling substances or fluorescent labeling substances can be used. Typical enzyme labeling substances include, for example, peroxidase (POX), chymotrypsinogen, procarboxypeptidase,
Glyceraldehyde-3-phosphate dehydrogenase, amylase, phosphorylase, D-Nase, P-
Examples include various enzyme reagents such as Nase. Examples of fluorescent labeling substances include fluorescein isothiocyanate (FITC), tetramethylrhodamine isothiocyanate (TRITC), substituted rhodamine isothiocyanate (XRITC), rhodamine B isothiocyanate, and dichlorotriazine fluorescein. (DTAF) etc. can be exemplified.
In addition, substances that have the ability to specifically bind to antibodies and become labeling agents by binding with such substances include:
For example, "Protein A" (ProA, Pharmacia), sheep anti-human immunoglobulin G antibody, rabbit anti-human immunoglobulin G antibody, goat anti-human immunoglobulin G antibody, mouse anti-human immunoglobulin G antibody, rat anti-human immunoglobulin G antibody, Examples include anti-human immunoglobulin G antibodies such as globulin G antibodies. A variety of conjugates of a substance capable of specifically binding to the above-mentioned antibody and a labeling substance have already been prepared and commercially available, and in the present invention, various commercially available conjugates may be used as the labeling agent. Commonly known methods [BFERLANGER et al., Acta. Endocrinol.
Suppl., 168 , 206 (1972), and MHKAROL et al.
Proc. Nat. Acad. Sci., USA, 57 , 713 (1967)], a new conjugate may be created and used. For example, when using an enzyme-labeled substance in the above preparation method, this and the above-mentioned ProA or anti-human immunoglobulin G antibody are mixed in a buffer solution of pH 4 to 6 at around room temperature in the presence of an appropriate oxidizing agent such as NaIO 4 . This is carried out by coupling reaction for 2 to 5 hours and then reducing with a suitable reducing agent such as NaBH4 .
The ratio of each reagent to be used is approximately 1 to 3 moles of the enzyme labeling substance and approximately 100 to 300 moles of the oxidizing agent per 1 mole of ProA or anti-human immunoglobulin G antibody, and the reducing agent is the oxidizing agent. Appropriately, the amount is about 1 to 2 times the mole. In addition, when creating a fluorescent labeling agent using a fluorescent labeling substance, place the fluorescent labeling substance in water or physiological saline with a pH of 6 to 8, and store it at around 0°C to room temperature.
About 0.5~ with ProA or anti-human immunoglobulin G antibody
It is enough to react for 3 hours [Fluorescent Antibody Method, Medical Chemistry Experimental Method Course, No. 4, pp. 263-270, 1st edition published in 1972, Nakayama Shoten]. The appropriate amount of fluorescent labeling substance to be used is generally about 1/50 times the weight of ProA or anti-human immunoglobulin G antibody. In the present invention, the complex consisting of an insoluble antigen, a test serum (ATLA antibody), and a labeling agent is measured according to a conventional method depending on the labeling substance in the labeling agent used. This is done by determining enzyme activity or fluorescent activity). Thus, according to the present invention, a large amount of test serum can be
