Follistatin-344 Research Peptide — 1mg Lyophilized
Follistatin-344 is a specific isoform of Follistatin, a secreted glycoprotein that functions as a potent antagonist of activin, myostatin, and several other TGF-β superfamily members. With a molecular weight of approximately 35,000 Da (as glycoprotein), Follistatin-344 contains 344 amino acids and is the predominant circulating isoform.
In vitro research applications include muscle cell differentiation studies, myostatin pathway research, and reproductive biology research involving activin and inhibin pathway modulation. Follistatin-344 is an important tool in understanding the TGF-β signaling superfamily.
