Human PD-1/LAG-3 (Luc) Jurkat Reporter cell

The Human PD-1/LAG-3 (Luc) Jurkat Reporter Cell was engineered to not only express the NFAT response element driving luciferase expressing systems, but also express the receptors full length human PD-1 (Gene ID: 5133) and LAG-3 (Gene ID: 3902), which can use to evaluate the synergistic effect of anti-human PD-1 and anti-human LAG-3 antibody. When co-cultured with target cells expressing human PD-L1 and MHCⅡ, the PD-1/PD-L1 and LAG-3/MHCⅡ interactions inhibit TCR signaling and NFAT-mediated luminescence. Blocking the PD-1/PD-L1 and LAG-3/MHCⅡ interactions by the stimultaneous addition of anti-PD-1 or anti-PD-L1 and anti-LAG-3 antibodies release the inhibitory signals and result in TCR activation and NFAT-mediated luminescence.
