    摘要: A highly sensitive and specific monoclonal-immuno-radiometric assay (M-IRMA) for hCG, using monoclonal antibodies (Mabs) directed against a 37-amino acid synthetic polypeptide analogous to the carboxyl terminus (CTP) of beta-hCG. Accordingly, in one embodiment, a method is described for the determination of human chorionic gonadotrThe present invention was made utilizing funds of the United States Government. The U.S. government is therefore granted a royalty-free, non-exclusive, world wide, paid-up license in this invention.
