FIELD: medicine, microbiology. SUBSTANCE: gamma-globulin showing immunity with respect to streptococcus of group A or gamma-globulin showing immunity with respect to streptococcus of group C is immobilized on polystyrene latex surface particles. Polystyrene latex is a mixture of polystyrene latex, dispersity - 0.20-0.22 mcm, and polystyrene latex, dispersity - 0.50-0.70 mcm, activated with zinc methacrylate. Preparation is stabilized in the presence of bovine serum albumin and polyethylene glycol and preserving agent were added to the preparation composition also. Method is carried out at condition of the definite ratio of the used components, given as g/l. Process is carried out in 0.01 M glycine-saline buffer, pH = 8.20-8.22. EFFECT: simplified method of using.
