ABSTRACT:
Antisera suitable for detecting the presence of human chorionic gonadotropin in body fluids by immunoassay are prepared by administering to a host animal an antigen comprising the .beta.-subunit of human chorionic gonadotropin which has been modified by cleaving and optionally conjugating the thus modified .beta.-subunit with a protein or hapten capable of enhancing the immunogenetic potency of the antigen. The antigens are also useful for the contraceptive purposes to terminate pregnancy.
