Follistatin 344 Peptide Description

Follistatin 344 was initially identified as a follicle-stimulating hormone inhibiting substance found in ovarian follicular fluid. FST is a high-affinity activin binding protein that can act as an activin antagonist. Two alternatively spliced follistatin mRNAs exist, encoding mature FS with 288 amino acid residues (FS-288) and 315 aa residues (FS-315). Natural FS purified from porcine ovaries is primarily a carboxy-terminal truncated form of FS-315 composed of 300 aa residues.

Follistatin 344 quickly gained popularity in the bodybuilding community as a potential supplement to rapidly increase lean tissue mass. Another protein, follistatin-related gene acts on similar pathways as FST regarding its muscle building properties. Increased lean tissue mass could give a bodybuilder an advantage in a competitive setting.

FST is a single chain gonadal protein that specifically inhibits follicle stimulating hormone release. The single FST gene encodes two isoforms Follistatin 317 and Follistatin 344 containing 317 and 344 amino acids respectively, resulting from alternative splicing of the precursor mRNA. There is evidence linking polycystic ovary syndrome and follistatin. Follistatin binds directly to activin and functions as an activin antagonist. It specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone. Subunit : Monomer Subcellular Location : Secreted. Tissue Specificity : Isoform 1 is the predominant isoform in serum but is undetectable in follicular fluid.

Follistatin 344 Peptide Storage

Lyophilized Follistatin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FST should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
