    Product Information

    Product Description

    This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye under optimal conditions and tested in-house for direct flow cytometric analysis in human cells. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated TIGIT (E5Y1W) XP® Rabbit mAb #99567.

    Product Usage Information

    Flow Cytometry (Fixed/Permeabilized) 1:50

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Protocol

    Specificity / Sensitivity

    TIGIT (E5Y1W) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total TIGIT protein.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the carboxy terminus of human TIGIT protein. This antibody cross-reacts with an unidentified protein of 42 kDa in some cell extracts.

    Background

    T-cell immunoreceptor with Ig and ITIM domains (TIGIT), also known as VSIG9, VSTM3, and WUCAM, is a member of the poliovirus receptor family of immunoglobulin proteins (1-3). TIGIT is expressed at low levels on subsets of T cells and NK cells, and is upregulated at the protein level following activation of these cells (1-4). TIGIT marks exhausted T cells in the tumor microenvironment (5) and during human immunodeficiency virus (HIV) infection (6). Research has shown TIGIT interacts with several receptors expressed on antigen presenting cells, such as dendritic cells and macrophages, as well as tumor cells and cells of the microenvironment. TIGIT binds with high affinity to PVR/CD155, and with low affinity to Nectin-2/CD112 and Nectin-3/CD113 (2,4,7). Upon binding to its ligands, TIGIT suppresses T cell activation, and inhibits T and NK cell cytotoxicity. This inhibition can be blocked using monoclonal antibodies directed at the extracellular domain of TIGIT, resulting in rejuvenated antigen-specific CD8+ T cell responses in tumors and during HIV infection (5,6,8). Three potential isoforms of TIGIT have been computationally mapped (9).
