Follistatin 344 (95%)
Also known as: FST344, Follistatin isoform 344
Recombinant 344-amino-acid isoform of follistatin, the endogenous activin and myostatin antagonist.
Follistatin is an endogenous glycoprotein that binds and neutralizes members of the TGF-β superfamily — most notably activin and myostatin (GDF-8).
The FST344 isoform is the longer, tissue-associated variant, as opposed to the circulating FST315 form.In the research literature, follistatin is a standard tool for investigating myostatin and activin signaling pathways, with implications for myogenic research, muscle-mass biology, and broader TGF-β-superfamily pharmacology.
Published work spans in-vitro binding studies, cell-culture experiments, and animal models of muscle-growth dynamics.The Novera catalog entry specifies 95% purity — a standard research-grade specification that reflects the complexity of producing and purifying a 344-residue glycoprotein.

Follistatin 344 is a single-chain glycoprotein that binds and neutralizes activin and myostatin, key regulators of muscle growth. This 95% purity grade is used in research studying muscle hypertrophy, reproductive biology, and fibrosis.
