Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS, 5% trehalose and mannitol. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human PD-L1, His (HEK293-expressed) (rHuPD-L1, His) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Human PD-L1, His (HEK293-expressed) (rHuPD-L1, His) 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 Programmed death-ligand 1 (PD-L1) has been speculated to play a major role in suppressing the adaptive arm of immune system during particular events such as pregnancy, tissue allografts, autoimmune disease and other disease states such as hepatitis. Normally the adaptive immune system reacts to antigens that are associated with immune system activation by exogenous or endogenous danger signals[1]. |
