7 Background:
Follistatin belongs to a group of structurally-diverse diffusible proteins that binds to TGF-beta 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-beta1. 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.
8 Storage&Stability：
Avoid repeated freeze and thaw cycle.Store at 2-8℃ for delivery and store at -20 or -70℃ for future use. The loss rate of the target protein which describes the stability was determined by accelerated thermal degradation test.That is to incubate the protein at 37℃ for 48h and no obvious degradation and precipitation were observed.The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
