B7-H3 ELISA Kits

B7-H3 is an immunoglobulin superfamily protein that is expressed by osteoblasts, fibroblasts, ciliated respiratory epithelial cells, anterior pituitary progenitor cells, first trimester extravillous trophoblasts, and multiple tumor cells. It is induced on activated dendritic cells (DC), skeletal muscle myocytes, and monocytes. B7-H3 can both stimulate and inhibit immune cell activation. As a co-stimulator, B7-H3 augments macrophage activation and promotes proliferation and cytokine secretion by ...
