Human LAG-3 (Luc) Jurkat Reporter Cell

The Human LAG-3 (Luc) Jurkat Reporter Cell was engineered to not only express the NFAT response element driving luciferase expressing systems, but also express the receptor full length human LAG-3 (Gene ID: 3902), which can use to evaluate the potency of LAG-3 blockade. When co-cultured with target cells expressing human MHCⅡ, the LAG-3/MHCⅡ interaction inhibits TCR signaling and NFAT-mediated luminescence. Blocking the LAG-3/MHCⅡ interaction by anti-LAG-3 antibodies releases the inhibitory signals and results in TCR activation and NFAT-mediated luminescence.
