Abstract

ABSTRACT: A mouse fused splenic cell line producing antibody that induces agglutination of human sperm was cultivated. The antibody was localized to the midpiece and tail of human spermatozoa by an indirect immunofluorescence method. The interacting antigen was identified in a sperm membrane protein preparation by SDS gel/protein blot immunofluorescence method. The molecular weight of the antigen was in the vicinity of 84 Kdaltons.
