Description
The TX99 monoclonal antibody specifically binds to T cell immunoreceptor with Ig and ITIM domains (TIGIT), which is also known as V-set and transmembrane domain-containing protein 3 (Vstm3). TIGIT is a 26-kDa, type I transmembrane glycoprotein that belongs to the poliovirus receptor (PVR) family. TIGIT is expressed on activated and memory CD4+ T cells and CD8+ T cells, follicular T helper cells, regulatory T cells, and NK cells. Its ligands include the poliovirus receptor (PVR, aka, CD155), poliovirus receptor-related protein 2 (PVRL2, aka, CD112), and poliovirus receptor-related protein 3 (PVRL3, CD113). TIGIT functions as a negative regulator of T cell and NK cell responses including proliferation, cytotoxicity, and the production of proinflammatory cytokines. TIGIT-deficient mice are reportedly more susceptible to developing autoimmune diseases in certain model systems.
Put all BD® AbSeq Reagents to be pooled into a Latch Rack for 500 µL Tubes (Thermo Fisher Scientific Cat. No. 4900). Arrange the tubes so that they can be easily uncapped and re-capped with an 8-Channel Screw Cap Tube Capper (Thermo Fisher Scientific Cat. No. 4105MAT) and the reagents aliquoted with a multi-channel pipette. BD® AbSeq tubes should be centrifuged for ≥ 30 seconds at 400 × g to ensure removal of any content in the cap/tube threads prior to the first opening.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography and conjugated to BD® AbSeq oligonucleotide under optimal conditions.
1. This reagent has been pre-diluted for use at the recommended volume per test. Typical use is 2 µl for 1 × 10^6 cells in a 200-µl staining reaction.
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
3. 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.
4. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
