Research compound
Follistatin
Follistatin is an endogenous glycoprotein that operates as a high-affinity sequestration factor for activin A and myostatin (GDF-8), preventing ligand access to type II TGF-beta receptors. The recombinant truncated isoforms FS288 and FS315 are the standard forms supplied for quantitative binding and ligand-neutralization assays across skeletal muscle and reproductive cell model systems. Follistatin is the foundational reference reagent for TGF-beta superfamily research, with particular utility in experimental designs that require selective myostatin pathway blockade. Supplied lyophilized for in vitro research use only.
