Prolactin Human Receptor Antagonist del 1-9, G129R mutant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 190 amino acids + an additional Ala at n-terminal and having a molecular mass of ~ 22 kDa. The Human Prolactin Receptor Antagonist is purified by proprietary chromatographic techniques.
fully biologically active as evidenced by inhibiting PRLR-induced proliferation of Nb2 cells or Baf3 cells stably transfected with hPRL receptors. It also interacts at 1:1 molar ratio with human prolactin receptor extracellular domain as documented by SEC and SPR (Biacore analysis).
