Follistatin is a naturally‑derived glycoprotein peptide widely studied in biochemical and pre‑clinical research fields. Encoded by the FST gene, it exists in multiple isoforms including FS‑344, FS‑315 and FS‑288, each showing distinct structural features and tissue‑related distribution characteristicsPMC. As an important antagonist against several ligands from the TGF‑β superfamily, it mainly binds and neutralizes myostatin (GDF‑8) and activin molecules, blocking these signalling molecules from connecting with corresponding cell‑surface receptors.
Myostatin acts as a natural negative regulator that constrains skeletal muscle development in organisms. By suppressing myostatin bioactivity, follistatin removes such inhibitory signals, creating favourable conditions for satellite cell activation, cell proliferation and differentiation, which has drawn broad interest for research on muscle‑related biological mechanisms. Apart from myostatin modulation, follistatin also participates in multiple physiological pathways, involving tissue repair, inflammatory response modulation and endocrine‑related signal regulation across different body tissues.
Pre‑clinical laboratory observations have demonstrated notable biological responses of follistatin in animal models, inspiring further exploration into research directions such as muscle mass maintenance, sarcopenia‑related mechanisms and tissue regeneration study. Among common isoforms, FS‑344 serves as a well‑documented precursor variant, which can be processed into the active FS‑315 form inside biological systems, and it is the major form adopted for most peptide‑related laboratory investigations.
It is critical to note that follistatin materials offered are intended for laboratory research purposes only, not for human diagnostic, therapeutic or clinical application. No definite human clinical conclusions for practical usage have been fully established yet. Our recombinant follistatin peptide is produced under standardized manufacturing workflows, with strict quality control covering purity, molecular identity and stability. Lyophilized powder format helps secure long‑term storage performance. Researchers shall follow local regulatory requirements and standard lab operation protocols when handling this peptide material.
