in an attempt to further study various fragments of free and combined forms of hcg beta present in biological fluids , we performed one- and two-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis , followed by western immunoblotting using antipeptide antibodies directed to the hcg beta- ( 111-116 ) portion ( monoclonal antibody fb12 ) antiserum to the hcg beta ( 8-16 ) portion or antiserum which was specific for fragments ending at residue 47 .
