Invitrogen™ TIGIT Monoclonal Antibody (GIGD7), PE, eBioscience™, Invitrogen™

Beschreibung

Description: The GIGD7 monoclonal antibody reacts with mouse T cell immunoreceptor with Ig and ITIM domains (TIGIT, VSTM3, WUCAM), a 26 kDa protein that is a member of the poliovirus receptor (PVR) family. In mice, the expression of TIGIT has been reported in follicular T helper cells, while in humans, the expression of TIGIT has been reported on NK cells, regulatory T cells, follicular T helper cells, memory CD4+ T cells, and CD8+ T cells. TIGIT is not expressed on B cells or naive CD4+ T cells. TIGIT is upregulated on CD4+ T cells following activation. TIGIT can interact with certain members of the PVR and PVR-like families, including CD155, and also mediates the interaction of NK cells and T cells with antigen presenting cells, fibroblasts and endothelial cells that express PVR and PVR-like proteins. Applications Reported: This GIGD7 antibody has been reported for use in flow cytometric analysis. Applications Tested: This GIGD7 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.

TIGIT is a 26 kDa protein that belongs to the poliovirus receptor (PVR) family. It is expressed on NK cells, regulatory T cells, follicular T helper cells, memory CD4+ T cells, and CD8+ T cells, but not on B cells or naive CD4+ T cells. However, TIGIT can be upregulated on naive CD4+ T cells upon activation. TIGIT interacts with members of the PVR and PVR-like families, including CD155. This interaction mediates the engagement of NK and T cells with antigen-presenting cells, fibroblasts, and endothelial cells expressing PVR and PVR-like proteins. Binding of TIGIT to PVR leads to increased secretion of IL-10 and decreased secretion of IL-12B, promoting the generation of mature immunoregulatory dendritic cells and suppressing T cell activation. Through these interactions, TIGIT plays a significant role in modulating immune responses and maintaining immune homeostasis.
