It belongs to the IGF family of peptides, which also includes IGF-II and insulin. The gene expression of IGF-I is mainly regulated by Growth Hormone, and IGF-I executes its functions via signaling through transmembrane tyrosine receptors(IGF Receptors). Most circulating IFG-I is associated with the IGF Binding Protein 3 (IGFBP-3), and the IGFBPs may inhibit the actions of IGFs by competing against the IGF Receptors. IGF-I is active in post-natal and adult animals, and is crucial for somatic growth, as IGF-I null mice show marked retardation in utero. IGF-I is involved in the carcinogenesis, and related to the prostate cancer as well. Recombinant rat Insulin-like Growth Factor I (rrIGF-I) produced in E.coli is a single non-glycosylated polypeptide chain containing 71 amino acids. A fully biologically active molecule, rrIGF-I has a molecular mass of 7.8 kDa analyzed by reducing SDS-PAGE and is obtained by proprietary chromatographic techniques at GenScript.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882241233075,"sku":"BK0086-10","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882241265843,"sku":"BK0086-50","price":375.54,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_fc947aaf-345b-484b-80ca-e175fb8073c0.jpg?v=1702049887","url":"https:\/\/afsbio.com\/products\/recombinant-igf-i-rat-bk0086","provider":"AFSBio Inc.","version":"1.0","type":"link"}
