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 A chain Human Recombinant produced in E.Coli is a single， non-glycosylated， polypeptide chain containing 134 amino acids fragment （233-366） and having an amino-terminal hexahistidine tag， having a total molecular weight of 19.2 kDa.
The Inhibin-Alpha A chain is purified by standard chromatographic techniques.
