Description

Description: The monoclonal antibody MH5A reacts with a homolog of PD-1 (PD-1H) also known as VISTA. PD-1H is a 309 aa type I transmembrane protein that belongs to the CD28 superfamily. This cell surface receptor is expressed on nearly all hematopoietic cells except B cells. VISTA negatively regulates T cell responses by suppressing early TCR activation, inhibiting cell proliferation, and suppressing TH1 cytokine production. The MH5A antibody has been reported to inhibit T cell infiltration in graft-versus-host disease mouse models. Applications Reported: This MH5A antibody has been reported for use in flow cytometric analysis. Applications Tested: This MH5A antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome. Fixation: Samples can be stored in IC Fixation Buffer (Product #...

VISTA (V-domain Ig containing suppressor of T-cell activation), also known as B7-H5 or PD-1H, is a product of the VSIR gene. Although VISTA bears sequence homology to PD-L1 it has a different expression pattern. In both mouse and humans, VISTA is expressed predominantly on hematopoietic cells with the highest densities on myeloid cells, and lower levels on T cells. It is usually absent on B cells. VISTA expressed by antigen presenting cells has been shown to directly suppress proliferation and cytokine production of CD4 and CD8 T cells, making it a target for cancer immunotherapy. The reported ligands of VISTA include CD28H, VSIG-3 and VSIG-8.
