Application

Anti-FST polyclonal antibody is used to tag follistatin protein for detection and quantitation by Western blotting and in cells and tissues by immunohistochemical (IHC) techniques. It is used as a probe to study the possible roles of follistatin in the regulation of TGF-β superfamily mediated processes such as those regulated by myostatin/GDF8 and activin.

Biochem/physiol Actions

Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release.Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release. The single FST gene encodes two isoforms, FST317 and FST344 containing 317 and 344 amino acids respectively, resulting from alternative splicing of the precursor mRNA. In a study in which 37 candidate genes were tested for linkage and association with polycystic ovary syndrome (PCOS) or hyperandrogenemia in 150 families, evidence was found for linkage between PCOS and follistatin.

General description

Follistatin is an autocrine glycoprotein component of the inhibin-activin-follistatin axis that mediates many cellular processes via its ability to bind and neutralize members of the TGF-β superfamily such as activin and myostatin/GDF-8.
