antigenic similarities of chorionic gonadotropin from human ( hcg ) , chimpanzee ( chcg ) , gorilla ( gcg ) , orangutan ( orcg ) , baboon ( pacg ) , macaque ( mcg ) , and marmoset ( macg ) were investigated in a radioimmunoassay system using an antiserum ( rabbit h93 ) with antigenic determinants known to reside in the terminal 15 amino acid residues of the unique carboxyl-terminal peptide of hcgbeta , which makes it highly specific for hcg without crossreactivity to hlh .
