[Immunoenzyme analysis of human IgG in the kinetic mode].

A kinetic sandwich enzyme-linked immunosorbent assay for the detection of human IgG (used as a model antigen) has been developed. Rabbit antihuman IgG has been used both for coating polystyrene microtitration plates and for the preparation of the conjugate of anti-human IgG with horse-radish peroxidase. The kinetics of the reaction of the antigen and the antibody-peroxidase conjugate with the reagents immobilized on polystyrene plates has been studied. The assay is optimized with respect to its sensitivity and the duration of intervals for every stage of the assay. The optimal time of the assay is about 10-15 minutes. The correlation between sensitivity and the duration of every stage of the assay has been established.
