Follistatin 344 – Research-Grade Recombinant Peptide Fragment
Follistatin 344 (FS-344) is a recombinant peptide fragment corresponding to the 344-amino-acid isoform of the native follistatin protein. Peer-reviewed research, including findings indexed under PMID: 15653504, describes its role in activin-binding mechanisms, TGF-? superfamily modulation, and ligand competition within growth-regulatory biochemical networks. In controlled laboratory environments, FS-344 is used to investigate peptide–ligand interactions, receptor-binding dynamics, and growth factor regulatory pathways.
FS-344 is particularly valuable for in-vitro studies examining activin sequestration, myostatin-binding interactions, downstream SMAD signaling outcomes, and receptor-level modulation within the broader TGF-? regulatory architecture. Its recombinant structure provides high stability and reproducibility for biochemical assays, mechanistic research models, and protein–protein interaction mapping.
The lyophilized research-grade form ensures consistent quality and controlled handling for laboratory applications requiring precision in high-affinity ligand-binding studies and biochemical pathway exploration.
Important Information About This Research Product:
Your vials are not empty — the lyophilized material collects at the bottom. All products arrive as lyophilized powder requiring reconstitution. (Bacteriostatic water is not supplied.) Store in a cool, dry environment — short-term at 4°C, long-term at ?20°C. This material is strictly for laboratory research use only — no instructions for reconstitution, dosing, or administration can be provided.
