The present invention relates to a synthetic resin immunoassay device, and more particularly to a synthetic resin immunoassay device used for tests using serum containing antigens or antibodies, among tests using immune reactions. Examples of such immunological tests include syphilis serological tests using syphilis antigens (lipid antigens or pathogen antigens) and antiserum, autoantibody tests using immune reactions such as rheumatoid factor, antinuclear antibodies, and thyroid autoantibodies;
There are HLA tests such as immunoassays based on the agglutination reaction between incomplete antibodies (immunoglobulin) bound to red blood cells and anti-globulin serum, and immunoassays based on the reaction between human histocompatibility locus antigen and antiserum. The principle of HLA testing is that after reacting lymphocytes with anti-HLA serum, rabbit complement is added, and if the antigen and antibody on the lymphocytes match, the lymphocytes will be damaged and die. Life or death can be determined using a microscope. HLA antigens are controlled by genes located at loci on chromosomes, and are classified into A, B, C, D, and DR loci, and it has been revealed that there are extremely many types of antigens for each locus. There is. Therefore, the main focus of the operations in HLA testing is to prepare an immunological test tool containing these various antisera, and to inject and fix the test subject's leukocytes into this tool (typing). Conventionally, these antisera have been handled in liquid form, but storage and handling are complicated. For this reason, a method has been adopted in which the antiserum is lyophilized and adhered and fixed onto the immunological test instrument used for typing. The immunological testing tools used for HLA testing include:
It is generally made of synthetic resin and has many recesses formed on the plate surface. However, when the antiserum is freeze-dried and fixed on such a synthetic resin immunoassay device,
The adhesion of the freeze-dried serum to the surface of the concave portion is weak, and it easily peels off during storage and transportation, leading to errors in typing determination. In addition, in order to attach freeze-dried serum, it has been done to use dried serum that has been insufficiently frozen.
In this case, the freeze-dried serum adheres to the surface of the recess as a film with poor porosity, making it impossible to dissolve it quickly during the typing operation, and furthermore, the remaining moisture may cause the antibody titer to decline over time. There were some flaws that could easily occur. The present invention aims to eliminate the above-mentioned drawbacks, and its gist is that a large number of recesses are formed on the plate surface, and the surface of the recesses is
Low-temperature plasma treatment is performed so that the oxygen atom/carbon atomic ratio is in the range of 0.15 to 0.35 according to line photoelectron spectra, and the serum is injected into the recesses and then freeze-dried to inject the serum into the recesses. The present invention relates to a synthetic resin immunoassay device characterized in that it is used by attaching it to the device. Next, the synthetic resin immunoassay device of the present invention will be explained in more detail. Examples of the synthetic resins constituting the present invention include polystyrene, polymethyl methacrylate, polyvinyl chloride, polycarbonate, acrylonitrile-methyl acrylate copolymer, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer, acetyl cellulose, Examples include acetyl butyl cellulose, acetalized polyvinyl alcohol, polypropylene, ethylene-propylene copolymer, polyester, polymethylpentene-1, etc., but particularly preferred are polystyrene and styrene-1, which have a particularly remarkable treatment effect.
They are acrylonitrile copolymer, styrene-maleic anhydride copolymer, and polyvinyl chloride. These synthetic resins may contain fillers, colorants, stabilizers, and the like. The synthetic resin immunoassay device of the present invention can be formed into a shallow container shape, for example, as shown in FIGS. 1 and 2. In this case, a large number of recesses 3 are formed in the plate surface 2 at the bottom of the immunological test device 1, and a peripheral wall 4 is erected. Further, a lid 5 can be provided above the peripheral wall 4 if necessary. Furthermore, the synthetic resin immunoassay device of the present invention can be shaped into, for example, a plate, a sheet, a bottle, or the like. A low-temperature plasma treatment is performed on the surfaces of a large number of recesses 3 formed in the plate surface 2. Low-temperature plasma treatment involves generating low-temperature plasma by applying a high-frequency electric field, microwave electric field, or DC electric field to a low-pressure gas of 100 mmHg or less.
This plasma gas flow is brought into contact with the surface of the concave portion 2 of the immunoassay device 1, and according to the present invention, the oxygen atom/carbon atom ratio of the surface of the concave portion 2 according to the X-ray photoelectron spectrum is 0.15 to 0.35, preferably 0.20 to
The surface can be oxidized to within a limited range of 0.30 to significantly improve the adhesion of lyophilized serum. In this case, the oxygen atom/carbon atom ratio is
When it is smaller than 0.15, the adhesion of the freeze-dried serum tends to be poor, and when it is larger than 0.35, it tends to act on antibodies in the serum and lower the titer. FIG. 3 shows an example of a high frequency discharge low temperature plasma processing apparatus. Inside Belgear 11 is 1×10 -2 mmHg to 100mm
It is under a reduced pressure atmosphere of Hg, preferably 1×10 -1 mmHg to 50 mmHg, and the atmospheric gas is turned into plasma by a band (electrode) 13 connected to a high frequency generator 12. Atmospheric gas is supplied into the bell gear 11 from the gas introduction pipe 14 and exhausted from the gas exhaust pipe 15 by a vacuum pump (not shown), and the generated plasma gas flow is effectively applied to the surface of the recess 2 of the immunoassay device 1. Place the immunological test tool 1 in contact with the bell jar 11.
placed inside and subjected to low-temperature plasma treatment. In this case, when performing low temperature plasma treatment only on the surface of the recess 2 of the immunoassay test device 1, perform the low temperature plasma treatment with a covering plate provided with a large number of holes that match the recess 2 placed thereon. be able to. Recess 2 of immunoassay test device 1 treated in this way
The oxygen atom/carbon atomic ratio as an indicator of the degree of oxidation on the surface of Area of atomic Is peak Ac
It can be determined from the formula (Ao/Ac)×j. Here, j is a correction coefficient between elements, and j is 0.45 when MgKα rays are used as an X-ray source. According to the synthetic resin immunoassay device of the present invention, the surface of the numerous recesses formed on the plate surface is treated with low-temperature plasma to improve the adhesion of freeze-dried serum, so it does not peel off during storage or transportation. This prevents errors in typing judgment. In addition, since the adhesion of freeze-dried serum to the surface of the recess is excellent, it is possible to use freeze-dried serum that has been sufficiently frozen and dried and has a small residual amount of water, and the freeze-dried serum that adheres to the surface of the recess is highly porous. Therefore, the lysis during the typing operation is performed quickly, and the decrease in antibody titer over time is reduced. Example 1 A substantially mortar-shaped recess 3 having an opening diameter of 5 mm and a flat surface of 1 mm diameter at the bottom was formed on the plate surface 2 of the container-shaped immunological test device 1 shown in FIGS. 1 and 2. Sixty polystyrene resin immunoassay devices 1 (dimensions: 55 mm x 85 mm x 10 mm) were molded by injection molding. Next, this immunoassay test device 1 was subjected to low-temperature plasma treatment using an apparatus as shown in FIG. While maintaining the air pressure inside the Belgear 11 at 2 x 10 -1 mmHg, the processing conditions were high frequency output of 100 to 250 W and processing time of several minutes.
The surface oxygen atoms/
Treated products with various carbon atomic ratios were obtained. Next, the ratio was measured using an X-ray photoelectron analyzer ESCA650B (manufactured by Shimadzu Corporation) (X-ray source MgKα ray). After dispensing 1μ of standard HLA antiserum into the recess 2, freeze-vacuum dry (vacuum level 2 × 10 -2 Torr, 3
time). In order to examine the adhesion of this freeze-dried serum, the plate surface 2 was dropped three times from a height of 40 cm while being held horizontally, and the peeling of the freeze-dried serum was observed. Table 1 shows the relationship between the high frequency output during the above plasma treatment, the treatment time, the oxygen atom/carbon atomic ratio, and the number of recesses from which serum had peeled off among the 60 recesses in the drop test. In addition, for comparison, the same procedure as above was performed for those whose oxygen atom/carbon atomic ratio was outside the range of 0.15 to 0.35 and those that were not subjected to plasma treatment, and the results are also shown in Table 1. .
