Lyophilized recombinant human Insulin-like Growth Factor II (rhIGF-II) remains stable up to 6 months at -80°C from date of receipt. Upon reconstitution, rhIGF-II remains stable up to 2 weeks at 4°C or up to 3 months at -20°C. Usage :
This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. For research use only. Description :
Insulin-like Growth Factor II (IGF-II) is a single chain 7 kDa polypeptide, and shares a high degree of homology with insulin. 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.
