The target protein is expressed with sequence (Met1-Trp344) of Rat Follistatin\/FST (Accession #NP_036693.1) fused with a His tag at the C-terminus.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Fst, Follistatin, FS, Activin-binding protein\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P21674\u003c\/p\u003e\n\n\u003cp\u003eGeneID: 24373\u003c\/p\u003e\n\n\u003cp\u003eSpecies: Rat\u003c\/p\u003e\n\n\u003cp\u003ePurity: ≥ 90% as determined by SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eStorage: Store at -20 ℃. Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.\u003c\/p\u003e\n\n\u003cp\u003eBackground: Enables heparan sulfate proteoglycan binding activity. Predicted to be involved in hematopoietic progenitor cell differentiation; negative regulation of transcription by RNA polymerase II; and regulation of transmembrane receptor protein serine\/threonine kinase signaling pathway. Predicted to act upstream of or within several processes, including animal organ development; keratinocyte proliferation; and positive regulation of hair follicle development. Predicted to be located in cytoplasm and nucleus. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in polycystic ovary syndrome. Orthologous to human FST (follistatin).\u003c\/p\u003e\n\n\u003cp\u003eBio-Activity: Measured by its ability to neutralize Activin-mediated inhibition on MPC-11 cell proliferation.
