Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Murine Insulin-like Growth factor-1 (rMuIGF-1) to 100 µg/mL using ddH2O. Storage & Stability Lyophilized recombinant Murine Insulin-like Growth factor-1 (rMuIGF-1) 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) system has been shown to modulate growth in many tissues, such as nervous tissue, lymphoid tissue, reproductive tissue, smooth muscle, endothelium, and bone. Insulin-like Growth factor-1 (IGF-I) 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]. Insulin-like growth factor-1 (IGF-1) is a neurotrophic factor capable of mediating neuroprotective and neuroplasticity mechanisms. Targeted overexpression of IGF-1 enhances the generation of hippocampal newborn neurons in brain-injured mice[2]. |
