Active Recombinant Human/Mouse/Rat INHBA Protein (Gly311-Ser426), GMP Grade

• Cat.No.: INHBA-09HG
• Product Overview: GMP recombinant human/Mouse/Rat Activin A protein (Gly311-Ser426) without tag was expressed in Chinese Hamster Ovary cell line and manufactured and tested under cGMP guidelines.

Specification

• Description: This gene encodes a member of the TGF-beta (transforming growth factor-beta) superfamily of proteins. The encoded preproprotein is proteolytically processed to generate a subunit of the dimeric activin and inhibin protein complexes. These complexes activate and inhibit, respectively, follicle stimulating hormone secretion from the pituitary gland. The encoded protein also plays a role in eye, tooth and testis development. Elevated expression of this gene may be associated with cancer cachexia in human patients.
• Source: CHO
• Species: Human/Mouse/Rat
• Form: Disulfide-linked homodimer
• Bio-activity: Measured by its ability to induce hemoglobin expression in K562 human chronic myelogenous leukemia cells. The ED50 for this effect is 0.2-1.2 ng/mL.
  The specific activity of Recombinant Human/Mouse/Rat Activin A is >1000 units/mg, which is calibrated against the human Activin A WHO reference standard.
