Research Applications
- Follistatin-344 is the full-length 344-amino-acid isoform of follistatin that binds and neutralizes myostatin (GDF-8) and activins with high affinity.
- Used to study blockade of myostatin/activin signaling through activin type II receptors (ActRIIB) and the resulting relief of Smad2/3-mediated inhibition of muscle growth.
- Research applications include models of muscle atrophy, sarcopenia, and muscular dystrophy to evaluate myostatin antagonism on fiber size and muscle mass.
- Serves as a reference ligand for quantifying follistatin–myostatin binding kinetics and for developing myostatin-inhibitory research strategies.
