Product Specifications

Immunogen

Recognizes human Follistatin isoform FS288, raised against recombinant human FS288. (Uniprot: P19883)

Localization

Secreted.

Specificity

Follistatin is a single-chain glycosylated protein that inhibits follicle stimulating hormone (FSH) release. Alternative splicing of Follistatin mRNA yields two isoforms, FS315 and FS288. FS288 is the main cell-surface form and binds to surface heparin sulphate proteoglycans. FST/4282 recognizes recombinant human Follistatin 288, allowing for detection of FSH levels using various analysis methods. This antibody also works in a two site ELISA with FST/4281.

Background: Follistatin

FST, also known as Follistatin, has a 344 amino acid long isoform that is 38 kDa and a short 317 amino acid that is 35 kDa, functions as an activin antagonist binding directly to it and inhibits the biosynthesis and secretion of pituitary follicle stimulating hormone (FSH). Studies of this protein are being performed in relation to polycystic ovary syndrome, pituitary adenoma, insulin resistance, Down syndrome, plasmacytoma, lymphocytic leukemia, pituitary tumor infertility, endometrial carcinoma, teratocarcinoma, azoospermia, meningitis, hepatocellular carcinoma, ovarian carcinoma, liver disease, endometriosis, prostate carcinoma, prostatitis, ovarian cancer, and adenoma. This protein has been also shown to have interactions with ANG, DIP2A, BMP4, FN1, and TXN in signal transduction activin A signaling regulation and TGF-beta signaling pathways.
