Reconstitute the lyophilized recombinant Human Insulin-like Growth factor-2 (rHuIGF-2) to 100 μg/mL using ddH2O. Storage & Stability
Lyophilized recombinant Human Insulin-like Growth factor-2 (rHuIGF-2) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
Insulin-like growth factor (IGF) modulates growth in many tissues, such as nervous tissue, lymphoid tissue, reproductive tissue, smooth muscle, endothelium, and bone. Human Insulin-like Growth factor-2 (IGF-II) is produced by osteoblasts, and its mitogenic effects are mediated by their binding to the IGF plasma membrane receptors. The IGF type 1 receptor binding to both IGF-I and IGF-II, is thought to be the predominate receptor involved in mediating the effects of these growth factors in most cell types, including osteoblasts[1]. |
