Preparation And Storage

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. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.

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

When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
Researchers should determine the optimal concentration of this reagent for their individual applications.
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.
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.
An isotype control should be used at the same concentration as the antibody of interest.
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.
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

Antibody Details

741182

The 741182 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.

Format Details

RB780

The BD Horizon RealBlue™ 780 (RB780) Dye is part of the BD family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 781-nm. Driven by BD innovation, RB780 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors.
