Description
Follistatin, human recombinant is available at Gentaur for Next week delivery.
An autocrine glycoprotein involved in binding and bioneutralization of members of the TGF-β superfamily
Biomolecule/Target:
Alternates names: FST, FS, Activin-binding protein
Synonyms: FST, FS, Activin-binding protein
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.
Reconstitution Instructions: Reconstitute in H₂O to a concentration of 0.1-1.0 µg/µl. The solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or –20°C for future use.
