Description / ovine Prolactin antagonist (G129R) protein
Recombinant ovine prolactin, G129R mutein is one polypeptide chain containing 199 amino and an additional Ala at N-terminus acids and having a molecular mass of ~ 23 kDa, was purified by proprietary chromatographic techniques (no published information). It is available in two forms: as full size protein and it its DEL 9 aa truncated form from its N-terminus which has higher inhibitory activity.
