title: [Determination of the concentration of active centers and the antibody heterogeneity index by using the precipitation in fluid reaction].
abstract: Equivalence zone in the precipitation test was characterized by the fact that the number of the antigen determinants was equal to the number of active antibodies centres, irrespective of the heterogeneity of the latter. This permits to assess the antibody concentration in the values of the antigen valency. The new method of determination of the antibody heterogeneity index is based on recording the titre of the antigen and antibodies in the equivalence zone.
