Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against 10 mM PB, pH 8.0, 150 mM NaCl. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human 4-1BBR/TNFRSF9 (rHu4-1BBR/TNFRSF9) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA. Storage & Stability Lyophilized recombinant Human 4-1BBR/TNFRSF9 (rHu4-1BBR/TNFRSF9) 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 Recombinant Human 4-1BBRTNFRSF9 (CD137) is an inducible T cell molecule belonging to the TNF receptor superfamily. It has been shown that signaling through CD137 by either its natural ligand, 4-1BBL, or by agonistic Ab’s costimulates activation of CD4+ and CD8+ T cells in a CD28-independent fashion, leading to activation of the NF-κB, c-Jun NH2-terminal kinase/stress-activated protein kinase (JNK/SAPK), and p38 signaling pathways. In addition to its role in promoting the expansion of antigen-specific T cells, CD137 signaling may also prevent activation-induced death of CD8+ T cells[1]. |
