Follistatin 344 is a glycoprotein fragment known to inhibit activin and myostatin, two proteins that regulate muscle growth and reproductive signaling.
Follistatin binds these ligands to prevent receptor activation, and is widely studied in muscle regeneration, metabolic signaling, and endocrine modulation models. This 344-amino acid isoform is provided in highly pure, recombinant form for consistent use in molecular signaling assays.
