Follistatin 344 1mg is a research-grade follistatin isoform from Peptide Sciences, used in studies of the myostatin and activin signalling pathways.
Follistatin and Myostatin Research
Follistatin is a glycoprotein that binds and neutralises members of the TGF-beta family, including myostatin and activin. Because myostatin limits muscle growth, follistatin is a central tool in muscle-biology research. FST-344 is the precursor isoform that is processed into FST-315, and research on gene-delivered follistatin has explored muscle mass in animal models.
