{"product_id":"follistatin-1mg","title":"Follistatin (1mg)","description":"\u003cp\u003eFollistatin is a naturally occurring glycoprotein that is considered to be present in almost all tissues. It is considered an autocrine chemical, meaning that the cell produces a chemical messenger through a cell signal, which binds to its autocrine receptors, resulting in cell modification.\u003csup\u003e(1)\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eFollistatin naturally occurs in two isoforms, FST 317 and FST 344, each containing 288 and 315 amino acids, respectively. These two isoforms may be produced through an alternative splicing process of the mRNA.\u003csup\u003e(2)\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eTheir names are based on the parent molecules from which they are derived and contain 317 and 344 amino acids, respectively. Follistatin is considered to be the predominantly expressed molecule in most tissues, while the Follistatin-317 isoform may account for less than 5% of the encoded mRNA.\u003c\/p\u003e\n\u003cp\u003eFollistatin is a synthetic version of the endogenous Follistatin protein isoform. Although the number of amino acids differs in Follistatin isoforms, at its core, the protein comprises 63 amino acid residues and three domains: FSD1, FSD2, and FSD3, with an identical structure in the synthetic peptide.\u003csup\u003e(3)\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eThese domains comprise 73-77 amino acid residues and are characterized by 10 conserved cysteine residues.\u003c\/p\u003e\n\u003cp data-end=\"1421\" data-start=\"1321\"\u003e\u003cstrong\u003eWarning: \u003c\/strong\u003eSterile glass vial\u003c\/p\u003e","brand":"5X Performance Built by Terrance Tyrrell","offers":[{"title":"3ml","offer_id":52810014097726,"sku":null,"price":390.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0943\/3982\/5982\/files\/Follistatin.png?v=1767095330","url":"https:\/\/v0nuk1-7k.myshopify.com\/products\/follistatin-1mg","provider":"5X Performance ","version":"1.0","type":"link"}
