Inhibins are dimeric peptide hormones produced by female ovarian granulose cells and male Sertoli cells as well as a variety of other tissues. Inhibins have two isoforms, A and B, with the same alpha subunit but different beta subunits. Inhibin A is a dimer of alpha and beta A subunits, inhibin B is a dimer of alpha and beta B subunits. Inhibins are thought to inhibit the production of follicle-stimulating hormone (FSH) by the pituitary gland. In addition, Inhibins are also thought to play a role in the control of gametogenesis, and embryonic and fetal development. Human recombinant Inhibin-alpha produced in E. coli is a non-glycosylated, polypeptide chain of 264 amino acids comprising both A and B chains and having a molecular mass of 33.5 kDa. The Inhibin-alpha is fused with an amino-terminal hexahistidine tag and has been purified by standard chromatographic techniques.

Please centrifuge product briefly before opening vial. The dissolved protein can be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store frozen at -20°C for longer periods of time. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
