Mouse B7-H2, also known as CD275, is expressed by antigen presenting cells, including B cells, monocytes/macrophages, and dendritic cells. It binds to the ICOS molecule. The interaction of ICOS/B7-H2 plays an important role in the T cell costimulation pathway. Mouse B7-H2 Recombinant Protein is purified B7-H2 produced in yeast.
