Prolactin Ovine Antagonist Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 199 amino acids and an additional Ala at N-terminus and having a molecular mass of 23kDa. The mutant R129G is DES 9 amino acids truncated form from its N-terminus which has higher inhibitory activity.
Ovine Prolactin Antagonist is purified by proprietary chromatographic techniques.
Target Information
Source
Escherichia Coli.
Sequence Similarities
