Description
Follistatin-344 (FST-344) is a recombinant 344-amino-acid isoform of the naturally occurring glycoprotein follistatin, with an approximate molecular weight of 38 kDa. As a full-length recombinant protein rather than a short synthetic peptide, it is not typically assigned a simple molecular formula or a single widely agreed CAS number; specifications should be confirmed against the certificate of analysis for this batch.
Research on FST-344 has examined its high-affinity binding to members of the TGF-beta superfamily, including myostatin and activin, and its role in modulating downstream Smad-pathway signaling in cell culture and animal models of muscle biology.
Supplied as a lyophilized powder for reconstitution, each batch is analyzed by HPLC and/or SDS-PAGE to confirm purity and identity.
For laboratory research use only. Not for human or veterinary use, and not intended for diagnostic or therapeutic application.
