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 Mouse Fibroblast Growth Factor-18 (rMuFGF-18) to 100 μg/mL using ddH2O. Storage & Stability Lyophilized recombinant Mouse Fibroblast Growth Factor-18 (rMuFGF-18) 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 Mouse Fibroblast Growth Factor-18 (FGF18) is a trophic factor for mature chondrocytes and their progenitors[1]. FGF18 has been reported to have significant anabolic effects on cartilage. FGF18 plays a central role in skeletal growth and development. Mice lacking Fgf18 exhibit malformations in cartilage and bone, including delayed closure of the calvarial sutures, enlargement of the proliferating and hypertrophic zones in the growth plate of long bones, defects in joint development, and delays in osteogenic differentiation[2]. |
