Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against 20 mM Tris and 150 mM NaCl, pH 8.0. Endotoxin Level <1.0 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human RANK L/TNFSF11 (rHuRANK L/TNFSF11) to 100 µg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human RANK L/TNFSF11 (rHuRANK L/TNFSF11) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week 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 Receptor activator of NF-κB ligand (RANKL), its cellular receptor, receptor activator of NF-κB (RANK), and the decoy receptor osteoprotegerin (OPG) constitute a novel cytokine system. RANKL produced by osteoblastic lineage cells and activated T lymphocytes is the essential factor for osteoclast formation, fusion, activation, and survival, thus resulting in bone resorption and bone loss. RANKL activates its specific receptor, RANK located on osteoclasts and dendritic cells, and its signaling cascade involves stimulation of the c-jun, NF-κB, and serine/threonine kinase PKB/Akt pathways[1]. |
