B7-H5, also known as VISTA, is one of the negative immune checkpoints of the B7 family. B7-H5 which is the most conserved among the B7 membersis mainly expressed in myeloid cells such as macrophages, monocytes, dendritic cells, and T cells VISTA is a type I transmembrane protein consisting of a single N-terminal immunoglobulin (Ig) V domain, an approximately 30 amino acid (aa) stalk, a transmembrane domain, and a 95 aa cytoplasmic tail. It can regulate a variety of immune cells, including B cells, T cells, and endothelial cells by binding to its putative receptor(s) on these cells. The expression of B7-H5 is closely related to the diagnosis, severity and prognosis of tumors.
Protein G Chip captured VSIG3/IGSF11 Fc Chimera Protein, Human (Cat. No. UA010571), can bind B7-H5/VISTA His Tag Protein, Human (Cat. No. UA010040) with an affinity constant of 0.43μM as determined in SPR assay.
