Clone TgMab-2 (RUO)

Multicolor flow cytometric analysis of TIGIT expression on Human peripheral blood leukocytes. Fresh whole blood was treated with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899) to lyse erythrocytes. After washing, the leukocytes were preincubated with BD Pharmingen™ Human BD Fc Block™ (Cat. No. 564219/564220) and then stained with APC Mouse Anti-Human CD56 (NCAM-1) [Cat. No. 555518; Middle Plots], BD Horizon™ BUV395 Mouse Anti-Human CD4 (Cat. No. 564724), and BD Horizon™ BV421 Mouse Anti-Human CD45RO (Cat. No. 562641/562649; Right Plots) antibodies, and with either BD Horizon™ PE-CF594 Mouse IgG1, κ Isotype Control (Cat. No. 562292; Top Plots) or BD Horizon™ PE-CF594 Mouse Anti-Human TIGIT antibody (Cat. No. 569863/569939; Bottom Plots) as indicated. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Left Plots: The pseudocolor density plot showing the correlated expression of TIGIT (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals was derived from gated events with the forward and side light-scatter characteristics of viable leukocyte populations.

Middle Plots: The pseudocolor density plot showing the correlated expression of TIGIT (or Ig Isotype control staining) versus CD56 was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes.

Right Plots: The pseudocolor density plot showing the correlated expression of TIGIT (or Ig Isotype control staining) versus CD45RO was derived from CD4-positive gated events with the forward and side light-scatter characteristics of viable lymphocytes.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Do not freeze.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
An isotype control should be used at the same concentration as the antibody of interest.

When excited by the yellow-green (561-nm) laser, the fluorescence may be brighter than when excited by the blue (488-nm) laser.

Antibody Details

TgMab-2

The TgMab-2 monoclonal antibody specifically recognizes TIGIT (T cell Immunoreceptor with Ig and ITIM domains) which is also known as Vstm3 (V-set and transmembrane domain-containing 3), Vsig9 (V-set and Ig domain-containing 9) and WUCAM (Washington University Cell Adhesion Molecule). TIGIT is a 30-34 kDa single pass type I transmembrane glycoprotein that belongs to the CD28 family within the Ig superfamily. TIGIT has an extracellular region with a V-type Ig-like domain, transmembrane sequence, and a cytoplasmic domain with an immunoreceptor tyrosine-based inhibitory motif (ITIM). TIGIT is expressed on NK cells and subsets of activated and memory T cells, regulatory T cells (Treg), and T follicular helper (Tfh) cells. TIGIT binds to CD112 (PVRL2/Nectin-2) and CD155 (PVR/Necl-5) that are expressed on dendritic cells (DC), endothelial cells, fibroblasts, and some tumor cells and can induce IL-10 release and inhibition of IL-12 production. Ligand-bound TIGIT downregulates TCR-mediated T cell activation and proliferation and can block NK cell-mediated cytotoxicity.

PE-CF594

BD Horizon™ PE-CF594 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496-nm and 566-nm and an acceptor dye with an emission maximum (Em Max) at 615-nm. PE-CF594, driven by BD innovation, is designed to be excited by the blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and detected using an optical filter centered near 615 nm (e.g., a 610/20-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and the acceptor dye can be excited by the green (532-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: PE-CF594
