Relationship of Isoantigens of Rabbit Spermatozoa to Erythrocytic Antigens

Abstract

Summary. By cross matching the bloods of eighteen rabbits, the relative blood group pattern was determined. Further, by using three typing sera (anti-A, -D, and -F sera) the presence of these antigens on red cells was determined. The agglutination pattern of the sera of the eighteen rabbits with spermatozoa from seven rabbits of the group and the absorption of positive sera with red cells and spermatozoa showed that no common antigens existed between red cells and spermatozoa. The absence of common antigen between red cells and spermatozoa in rabbits was further confirmed by mixed agglutination of these two kinds of cells using natural haemagglutinins as well as specific blood typing immune sera.

The Nature of the Isoantigen of Rabbit Spermatozoa That Reacts With the Spermagglutinin of Normal Homologous Serum

“…The age, breed and sex of the rabbits used for serum collection were from the same colony studied earlier (Padma, 1972c). Bucks Cl and A6 were albinos while Bucks 16 and 21 belonged to a black and white breed.…”
