Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against 50 mM HEPES, 750 mM NaCl, pH 7.5. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Fibroblast Growth Factor 4 (rHuFGF-4) to 100 µg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human Fibroblast Growth Factor 4 (rHuFGF-4) 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 Fibroblast Growth Factor 4 (EGF 4) is a member of the FGF family that transforms 3T3 cells with high efficiency, stimulates endothelial cell proliferation, migration, and protease production, and shows angiogenic activity[1]. |
