Follistatin 344 – 1mg

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-β 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-β 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.
