Cynomolgus B7-H2/ICOSLG Protein (BH7-CM172) Summary

Product Description

 Recombinant Cynomolgus B7-H2/ICOSLG Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Asp19-Thr256.

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.
