Background Information: Follistatin belongs to a group of structurally-diverse diffusible proteins that binds to TGF-β ligands and inhibit their activity by hindering access to signaling receptors. This naturally occurring antagonist binds to Activin, BMP-2,-4,-6,-7, Myostatin, GDF-11, and TGF-β1. Follistatin is expressed in the pituitary, ovaries, decidual cells of the endometrium, and in some other tissues. Recombinant human Follistatin is a 31.5 kDa protein containing 288 amino acids including 36 cysteine residues.

Handling: Centrifuge the vial prior to opening.

Usage: For Research Use Only! Not to be used in humans.
