ISOREACTIONS, serum reactions, in which both the antibody and the antigen belong to the same animal species. In this way, isoreactions differ from ordinary hetero-reactions of immunity, where the antigen and antibody have different species origins. Isoreactions are characteristic of normal human serum and exhibit clear specificity, expressed in the fact that an isoreaction occurs only when the is antibody of the serum encounters its corresponding antigen (Landsteiner). Among I., the reaction of isoagglutination has acquired the greatest theoretical and practical significance (see Agglutination). ISOTELA
