      • 產品描述:

        CUSABIO expressed the human TIGIT residues 22-141 carrying a C-terminal hFc-Myc tag in mammalian cells. The product is the recombinant human TIGIT protein. It is an active protein with high purity (>96%, SDS-PAGE) and low endotoxin (<1.0 EU/ug protein, LAL method). It has an apparent molecular weight of 46 kDa due to glycosylation. In the FACS assay, this TIGIT protein can bind to 293F cell overexpressing human CD155. And it is in stock so that there is no preparation waiting period.

        TIGIT, a co-inhibitory molecule on T cells, exerts immunosuppressive effects by competing with CD226 for the same CD155 ligand. Accumulating roles demonstrate that TIGIT plays a key role in limiting adaptive and innate immunity against tumors.

      靶點詳情

      • 功能:
        Binds with high affinity to the poliovirus receptor (PVR) which causes increased secretion of IL10 and decreased secretion of IL12B and suppresses T-cell activation by promoting the generation of mature immunoregulatory dendritic cells.
