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-1, His (HEK293-expressed) (rHuPD-1, His) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Human PD-1, His (HEK293-expressed) (rHuPD-1, 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-1 (PD-1) is a receptor on T cells that has been shown to suppress activating signals from the T cell receptor when bound by either of its ligands, programmed death-ligand 1 (PD-L1) or PD-L2. When PD-1 expressing T cells contact cells expressing its ligands, functional activities in response to antigenic stimuli, including proliferation, cytokine secretion, and cytotoxicity are reduced[1]. |
