title: [Valency of antigenic erythrocyte diagnosticums and serum antibody affinity].
abstract: The Fab-fragments of antibodies were separated from the intact antibodies by their activity in serological reactions of eluate portins from Sephadex G-100. The valency of antigenic erythrocytic diagnostic agents was evaluated by their maximum ability bind Fab-fragments. The affinity of monovalent Fab-fragments was evaluated with antigenic erythrocytic diagnostic agents. A graphic and an analytical variants of determination of the average association constant by the suspension method have been developed.
