Compn for detecting physiological amounts - of antigens

摘要

The composition comprises a suspension of polymer particles having antibody activity and insol. in water, in an antiserum for the antigen, the particles being coated with an immunological amount of a specific or co-reactive antigen, the antiserum reacting with the antigen being in a concn such that a prozone effect is produced if the soln. is mixed with a normal sample where the antigen is absent but which produces an agglutination where the antigen is present in a physiological quantity.
