The Raji-Human CD155-Stable Cell Line is engineered to express full-length human CD155 (Uniprot: P15151-1), used to mimic cancer target cells. When co-cultured with human TIGIT Reporter Cell, the TIGIT/CD155 interaction inhibits TCR signaling and NFAT-mediated luminescence. Blocking the TIGIT/CD155 interaction by either anti-TIGIT or anti-CD155 antibodies releases the inhibitory signal and results in TCR activation and NFAT-mediated luminescence.
Useful for cell-based CD155 binding assay
CD155 (PVR, Poliovirus Receptor) is a transmembrane protein expressed on epithelial cells and tumor cells. It binds to DNAM-1 (activating) and TIGIT/CD96 (inhibitory) receptors on immune cells, modulating cytotoxicity and immune escape. Overexpression correlates with poor cancer prognosis.
