[Determination of human IgI allotypes by using a set of stable erythrocyte antigenic diagnostica of varying specificity].

Technology of preparing a set of stable antigenic diagnostic agents of commercial type for determination of genetic determinants of human IgG and antibodies to them in the human blood sera and in the animal hyperimmune sera was worked out. Antisera against some human IgG allotypes were prepared. The frequency of detection of individual IgG allotypes and antibodies to them in human sera was studied.
