Product Description |
Recombinant Mouse B7-H2/ICOSLG Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Glu47-Lys279. |
Product Background |
B7-H2, also known as B7-related protein (B7RP1), ICOS Ligand, and CD275, is an approximately 60 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. B7-H2 is a ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. |
