title: [Formation of complete and incomplete antibodies by rabbits immunized with sheep erythrocytes].
abstract: A parellel determination of incomplete and complete antibodies in rabbits immunized by various doses of sheep erythrocytes demonstrated that reduction of the titres of complete antibodies occurred more rapidly than that of imcomplete ones. Complete 7S-antibodies appeared in the blood of animals immunized with high doses of erythrocytes or after a repeated injection of low antigen doses. Incomplete 7S-antibodies are determined in the blood of rabbits after a primary immunization with high and with low doses of sheep erythrocytes, The titres of incomplete hemagglutinins were almost the same in the reaction with crude and trypsinized erythrocytes. As to the titres of complete hemagglutinins, they were greater in the reaction with trypsinized erythrocytes than in the reaction with crude cells, and approached the titres of incomplete antibodies.
