Follistatin
Follistatin is an endogenous glycoprotein that functions as a high-affinity activin-binding protein, sequestering activin A and myostatin (GDF-8) and preventing their propagation through type II TGF-beta receptors. Research preparations commonly employ the recombinant truncated forms FS288 or FS315 in binding and neutralization studies conducted in skeletal muscle and reproductive cell models. Its capacity to independently modulate both the activin and myostatin arms of TGF-beta signaling makes it a foundational tool in that superfamily's pharmacology research. Supplied lyophilized for in vitro research use only.
