During circulation in vivo, IGF-II is complexed to high affinity binding proteins, IGF Binding Proteins (IGFBP), which act as circulating reservoirs, transport IGF-II, and prolong the half life of IGF-II. The receptors of IGF-II (IGFRs) are transmembrane tyrosine receptors, and are heterotetrameric consisting of two α-subunits and two β-subunits. IGFRs execute their role via intracellullar signaling molecules, such as IRS, shc, and PI3K. The functions of IGF-II include promoting cell survival, growth, proliferation, differentiation and motility. In particular, IGF-II promotes proliferation, inhibits death, and stimulates transformation in breast cancer cells.Recombinant human Insulin-like Growth Factor II (rhIGF-II) produced in E.coli is a single non-glycosylated polypeptide chain containing 68 amino acids. A fully biologically active molecule, rhIGF-II has a molecular mass of 7.6 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":42882241331379,"sku":"BK0087-10","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882241364147,"sku":"BK0087-50","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_faab813f-20c5-46c7-b676-734198886a2b.jpg?v=1702049889","url":"https:\/\/afsbio.com\/products\/recombinant-igf-ii-human-bk0087","provider":"AFSBio Inc.","version":"1.0","type":"link"}
