Follistatin Antibody / FST / Activin Binding Protein (FS288 & FS315)

• Catalog Number: orb699730
• Category: Antibodies
• Description: 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/4281 is a clone raised against recombinant Fst 288, and is used in combination, commonly as the capture, with antibody < a href=../tds/follistatin-antibody-fst-4282-v8664>FST/4282 in a two site ELISA for the detection of Follistatin.
