More specifically, the present invention relates to γ-collidine; general formula () (In the formula, R 1 , R 2 , R 3 and R 4 are the same or different and represent a hydrogen atom or an alkyl group having 1 to 5 carbon atoms.) Imidazole or a derivative thereof; and the general formula () Propane 1,3 represented by (wherein, R 1 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms)
- An antigen or antibody sensitized latex reagent containing at least one compound selected from the group consisting of diol derivatives, further including γ-collidine; imidazole or a derivative thereof represented by the general formula (); The present invention relates to a method for stabilizing an antigen or antibody sensitized latex, which comprises coexisting at least one compound selected from the group consisting of propane 1,3-diol derivatives represented by the general formula (). The latex reagent of the present invention is useful as a reagent for measuring α-fetoprotein, C-reactive protein, fibrinogen, rheumatoid factor, immunoglobulin, and the like. When conventional latex reagents are stored for a long time, natural aggregation of latex particles occurs, making it impossible to accurately measure antigens or antibodies. As a result of various studies to improve the above drawbacks, after suspending an antigen or antibody sensitized latex in an aqueous solvent, γ-collidine; imidazole or its derivative represented by the general formula (); and the general formula ()
A latex reagent obtained by coexisting with at least one compound selected from the group consisting of propane 1,3-diol derivatives represented by It has been found that antigens or antibodies can be measured with high accuracy even after storage. The present invention will be explained in detail below. The antigen or antibody used in the present invention includes human immunoglobulin G, human immunoglobulin A,
Human immunoglobulin M, human γ-globulin, human serum albumin, α-fetoprotein, β 2 -microglobulin, myoglobin, C-
Examples include reactive protein, fibrinogen, and human chorionic gonadotropin. Latexes that sensitize antigens or antibodies include:
Examples include polystyrene, carboxylated polystyrene, polyvinyltoluene, styrene-butadiene copolymer, carboxylated styrene-butadiene copolymer, acrylic ester polymer, and methacrylic ester polymer. As the aqueous solvent, physiological saline, buffer solutions (glycine buffer, phosphate buffer, borate buffer, etc.), and combinations thereof are used. The alkyl group having 1 to 5 carbon atoms in the general formulas () and () includes a methyl group, an ethyl group, a propyl group, a butyl group, and the like. When producing latex reagents, for example, adsorption methods and covalent bonding methods can be used. When using the adsorption method, latex is added to an aqueous solvent in which the antigen or antibody is dissolved, stirred or shaken, and heated if necessary to sensitize the latex with the antigen or antibody. This sensitized latex is then separated by centrifugation and the supernatant is removed. The obtained sensitized latex was redispersed in an aqueous solvent, and then this dispersion was mixed with γ-collidine; imidazole or its derivative represented by the general formula (); and propane 1,3- represented by the general formula (). A latex reagent is obtained by adding and mixing at least one compound selected from the group consisting of diol derivatives. In addition, when using a covalent bonding method, a coupling agent is added to the suspension of carboxylated latex.
For example, water-soluble carbodiimide etc. at room temperature to 5°C.
Mix while stirring. Thereafter, an antigen or antibody dissolved in an aqueous solvent is added to this solution, mixed by stirring, and then centrifuged. The obtained antigen or antibody sensitized latex is redispersed in an aqueous solvent. Then, to this dispersion, at least one compound selected from the group consisting of γ-collidine; imidazole or its derivative represented by the general formula (); and a propane 1,3-diol derivative represented by the general formula () is added. , a latex reagent is obtained by mixing. The concentration of the sensitizing latex in the latex reagent obtained as described above is 0.01 to 5.0 w/v% (hereinafter, % means w/v%), preferably 0.05
~2.0%, γ-collidine, imidazole represented by the general formula () or its derivatives, or propane 1,3- represented by the general formula ()
The concentration of diol is in the range of 0.05 to 2.0%, preferably 0.1 to 1.0%. Examples are shown below. Example 1 Polystyrene latex with a particle size of 0.2 μm
To 5 ml of a suspension dispersed in 0.1M phosphate buffer (PH 8) to a concentration of 2.0%, 5 ml of a solution obtained by dissolving human γ-globulin in the above buffer (PH 8.0) to a concentration of 0.5% was added. Then, mix and sensitize by slowly stirring at 56°C for 1 hour. 0.1M glycine buffer (PH8.0) containing 0.1% bovine serum albumin after centrifugation
Then, the sensitized latex obtained above is redispersed so that the concentration is 0.5%. 10ml of this dispersed suspension
40μ of γ-collidine was slowly mixed with stirring, and 0.01g of sodium azide was added to obtain a reagent for determining rheumatoid factor. For comparison, a reagent with the above formulation without the addition of γ-collidine was prepared. When these two reagents are stored at about 4° C. for a long period of time, the degree of spontaneous aggregation of the suspension particles is determined from absorbance measurement using a spectrophotometer. Measurement is at wavelength 800n
m, optical path length 5 mm, and dilute the reagent 5 times with the above 0.1 M phosphate buffer (PH8) to use as a sample. The results are shown in Table 1.

を第２表に示す。[Table] Almost no change in absorbance was observed in the reagents obtained in the examples, which indicates that spontaneous aggregation of the sensitized latex particles did not occur. On the other hand, in the comparative example, the absorbance change was large and spontaneous aggregation occurred. Example 2 Carboxylated polystyrene latex (particle size 0.25 μm) was added to 6 ml of a suspension adjusted to a concentration of 1% with 0.1 M phosphate buffer-physiological saline (hereinafter referred to as PBS) (PH 7.0). 0.6 mg of 1-cyclohexyl
20 ml of 3-[2-morpholinyl-(4)-ethyl]carbodiimide-meth-P-toluenesulfonate
280μ of a solution dissolved in PBS is added while stirring at a constant temperature of 4°C. After 5 minutes, 2.2 ml of PBS containing 0.1% rabbit anti-C-reactive protein antiserum is added with gentle stirring, and stirring is continued at 4° C. for 24 hours to sensitize by covalent bonding. Then 10000
Perform centrifugation by rotating, discard the supernatant, and redisperse the resulting precipitate in PBS. Centrifuge again and redistribute the sensitized latex in PBS containing 0.1% bovine serum albumin to a concentration of 0.5%. Next, add 12μ of γ-collidine to 6ml of this suspension.
was added with gentle stirring, and 6 mg of sodium azide was further added and mixed to obtain a reagent for measuring C reaction protein. For comparison, a reagent without γ-collidine was also prepared at the same time. These two reagents are stored at 4°C to 7°C for 12 months, and the presence or absence of spontaneous aggregation is visually observed. When γ-collidine was added, almost no aggregation was observed.
Table 2 shows the results of dropping 25μ of human serum onto a glass slide plate, adding 25μ of the above-mentioned reagent after storage, and shaking for 2.5 minutes.The state of the agglutination reaction was determined visually.Table 2 shows the results.
