title: Isolation and properties of two fragments from plasmin digests of human choriomammotropin.
abstract: Two fragments have been isolated and characterized from plasmin digests of human choriomammotropin. It was shown that these two fragments were derived from the cleavage of the Arg-Arg (positions 133-134) and the Lys-Gln (positions 140--141) bonds of the hormone: one has 133 amino acids and the other 51 amino acids. Both fragments were biologically and immunologically inactive.
