Buy Follistatin 344 1mg Research Peptide OnlineFollistatin 344 is a naturally occurring glycoprotein classified as a myostatin antagonist in preclinical research contexts. This 344-amino-acid variant is studied in preclinical models for its potential to modulate growth factor signaling pathways, particularly through binding and sequestration of activin and myostatin ligands in non-human research contexts.Follistatin 344 Published Research SummaryThe primary mechanism of action involves competitive antagonism of transforming growth factor-beta (TGF-β) superfamily members. In cell culture and animal models, Follistatin 344 binds with high affinity to myostatin and activins, preventing their interaction with cognate receptors. Lee et al. (2005) demonstrated that Follistatin expression correlates with increased muscle fiber size in preclinical models through suppression of myostatin signaling.Follistatin 344 Mechanism of ActionPreclinical research utilizing knockout and transgenic animal models has shown that Follistatin 344 influences muscle growth and differentiation pathways. In vitro studies indicate the peptide acts through ActRIIB receptor antagonism, blocking downstream SMAD2/3 phosphorylation cascades. McCroskery et al. (2003) documented substantial increases in muscle mass in experimental animal models expressing elevated Follistatin levels, establishing the mechanistic relationship between Follistatin expression and muscle development.Follistatin 344 1mg Product Specifications & StorageFollistatin 344 is provided as lyophilized powder in 1mg vials containing pharmaceutical-grade peptide.
