Recombinant Human IGF-1Description :
The IGFs are mitogenic polypeptide growth factors that stimulate the proliferation and survival of various cell types including muscle, bone, and cartilage tissue in vitro. IGFs are predominantly produced by the liver, although a variety of tissues produce the IGFs at distinctive times. The IGFs belong to the Insulin gene family, which also contains insulin and relaxin. The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-II expression is influenced by placenta lactogen, while IGF-I expression is regulated by growth hormone. Both IGF-I and IGF-II signal through the tyrosine kinase type I receptor (IGF-IR), but, IGF-II can also signal through the IGF-II/Mannose-6-phosphate receptor. Mature IGFs are generated by proteolytic processing of inactive precursor proteins, which contain N-terminal and C-terminal propeptide regions. Recombinant human IGF-I and IGF-II are globular proteins containing 70 and 67 amino acids, respectively, and 3 intra-molecular disulfide bonds. 佰易聚生物商城提供上等的分子生物学试剂和试剂盒、美国联合碳化和美国光谱医学透析袋、培养基和培养耗材、细胞因子和细胞分离液、抗体和elisa试剂盒及常用生物试剂等,大量现货火爆促销中,欢迎登录www.ebioeasy.com或者拨打021-61805605,61805606，61805610洽谈选购！
