ABSTRACT
The characteristics of monoclonal antibodies developed against human spermatozoa are described. Out of 10 monoclonal antibodies 9 did not react in ELISA with human RBC, WBC, platelets, Raji cells nor mouse sperm. Four monoclonal antibodies reacted with monkey sperm and all 10 reacted with human seminal plasma. Monoclonal antibodies showed differential reactivity with pre- and post-capacitated sperm. Four monoclonal antibodies were able to agglutinate sperm whereas none of these were positive in sperm-immobilization assay. Interestingly, two monoclonal antibodies (MA-46 and MA-50) were able to block the attachment of pre-capacitated sperm to zona denuded hamster oocytes. MA-46 and MA-50 recognized in immunoblot spermatozoa antigens having apparent molecular weights of 14 and 20 K Da and greater than 200 K Da respectively. The monoclonal antibodies reported in this study will be useful in further delineating the spermatozoa antigens involved in regulation of fertility.
