PE anti-human VISTA (PD-1H) Antibody, VISTA, A17002B,BioLegend,378119

VISTA (V-domain Ig suppressor of T cell activation), also known as PD-1H, is a type I transmembrane protein with a single extracellular IgV domain. VISTA is expressed by a subset of T cells, macrophages, dendritic cells, neutrophils, and NK cells. It was reported that in certain tumor environment, there is low-pH dependent interaction between VISTA and PSGL1. However, the physiological binding partner for VISTA and the mechanism of its action are not clearly understood. VISTA is considered as a checkpoint regulator and a promising target for cancer immunotherapy.
