Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human B7-H3/ICOSLG, His (HEK293-expressed) (rHuB7-H3/ICOSLG, His) to 100 μg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Human B7-H3/ICOSLG, His (HEK293-expressed) (rHuB7-H3/ICOSLG, His) 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 As a member of the B7 family, inducible co-stimulator ligand (ICOSLG) expressed on tumor cell has been reported to have an important role in tumor immunity. As the counter ligand of ICOS, a CD28-related molecule, ICOSLG is expressed on professional antigen-presenting cell (APCs; such as dendritic cells (DCs) and B cells) and on some tumor cells (such as glioma cells and gastric carcinoma cells). ICOSLG is the only B7 family member that preferentially co-stimulates type 2T helper cell (Th2) responses, and interestingly, this unique molecule has a critical role in antitumor immunity. ICOSLG expression on solid tumors (implanted-transfected tumors) aids in both NK mediated and CD8+ cytotoxic T cell (CTL) activation and killing. Several studies using ICOSLG-transfected solid tumor cell lines found that ICOSLG induced CD8+ cytotoxic lymphocyte-mediated tumor regression[1]. |
