| Abstract: | Fragments of the IgG molecule, related to Fab, present in the blood serum of partially hepatectomized rabbits, have the property of intensifying the immune response of rabbits through xenogeneic erythrocytes. After simultaneous injection of sheep's erythrocytes and the Fab-like fragment into rabbits there was an increase in the number of antibody-producing cells in the spleen and in the titers of 19S and 7S hemagglutinins.Kursk Medical Institute.
