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.
Inhibin-Alpha Human Recombinant produced in E.Coli is a non-glycosylated， polypeptide chain containing 264 amino acids comprising of both A and B chains， having a molecular mass of 33.5 kDa.
The Inhibin-Alpha is fused with an amino-terminal hexahistidine tag.
The Inhibin-Alpha is purified by standard chromatographic techniques.
