Reconstitute the lyophilized recombinant Human TIGIT, Fc Chimera (HEK293-expressed) (rHuTIGIT, Fc Chimera) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability
Lyophilized recombinant Human TIGIT, Fc Chimera (HEK293-expressed) (rHuTIGIT, Fc Chimera) 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
T cell Ig and ITIM domain (TIGIT) is a transmembrane glycoprotein belonging to a poliovirus receptor family of type 1 proteins that also binds to CD155 and CD112 ligands. TIGIT is expressed on peripheral memory and regulatory CD4+ T cells and NK cells and is upregulated following activation on naive CD4+ T cells. CD155 is a high-affinity receptor for TIGIT expressed on monocytes and CD11c+ human dendritic cells (DCs). TIGIT contains an Ig-like V-type domain and an ITIM in its cytoplasmic domain, suggesting that receptor occupancy may trigger a negative signaling event[1]. |
