VISTA/B7-H5 Protein is a B7 family member that maintains T cell and myeloid quiescence and is a promising target for combination cancer immunotherapy. VISTA not only acts as a ligand expressed on antigenpresenting cells, but also functions as a receptor on T cells. VISTA inhibits T cell activation, proliferation, and cytokine production. VISTA/B7-H5 Protein, Cynomolgus (HEK293, Fc) is the recombinant cynomolgus-derived VISTA/B7-H5 protein, expressed by HEK293 , with C-hFc labeled tag.
