The triacontapeptide corresponding to sequence 116-145 of the beta-subunit of human chorionic gonadotropin (hCG) according to the amino acid sequence elucidated by Morgan was synthesized by successive azide condensation of 5 peptide fragments, followed by TFA [trifluoroacetic acid] treatment and catalytic hydrogenation. This peptide was conjugated with bovine serum albumin (BSA). A 1% binding of 125I-hCG was observed with the antiserum produced against the conjugate obtained above at a 1:500 dilution.
