Follistatin 1mg

Follistatin 344 is a recombinant, full-length protein analogue of human follistatin (FST) that is studied as a high-affinity binding protein for select TGF-β superfamily ligands, including activins and myostatin. Follistatin-344 protein research commonly focuses on how ligand sequestration alters downstream signaling networks that regulate cellular proliferation, differentiation, and tissue remodeling under controlled laboratory conditions. As a precursor-length construct, it is also used in experimental settings to examine isoform processing and the functional differences between full-length and shorter follistatin variants.
