Formulation Lyophilized after extensive dialysis against 20 mM PB, 150mM NaCl, pH 6.2. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstituted the lyophilized Human Insulin-like Growth Factor-Binding Protein 5 (rHuIGF-BP5) in ddH2O at 100 μg/mL. Storage & Stability Lyophilized recombinant Human Insulin-like Growth Factor-Binding Protein 5 (rHuIGF-BP5) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 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-Binding Proteins (IGFBPs) modulate the actions of secreted insulin-like growth facts (IGFs) by binding to them and increase the IGF halflife in the extracellular milieu and circulation by sequestering them in this bound form. IGFBPs either enhance or inhibit IGF actions on target cells; the individual IGFBPs either inhibit or potentiate IGF effects on osteoblasts in bone. Human Insulin-like Growth Factor-Binding Protein 5 (rhIGFBP-5) is a unique and most abundant IGFBP stored in bone, having a high specific binding affinity for hydroxyapatite and extracellular matrix proteins, therefore fixing it and its bound IGFs within bone. rhIGFBP-5 consistently stimulates osteoblast cell proliferation in vitro, thus increasing the number of osteoblasts[1]. |
