BV421 Mouse Anti-Mouse TIGIT
BV421 Mouse Anti-Mouse TIGIT

Two-color flow cytometric analysis of TIGIT expression on mouse splenocytes. Mouse splenic leucocytes were stimulated (3 days) with concanavalin A (ConA). The cells were harvested and preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with APC Hamster Anti-Mouse CD3e antibody (Cat. No. 553066/561826) and either BD Horizon™ BV421 Mouse IgG1 κ Isotype Control (Cat. No. 562438; Left Panel) or BD Horizon BV421 Mouse Anti-Mouse TIGIT antibody (Cat. No. 565270; Right Panel). Two-color flow cytometric contour plots showing the correlated expression of TIGIT (or Ig Isotype control staining) versus CD3 were derived from gated events with the forward and side-light scattering characteristics of viable activated leucocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

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 with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

1G9

The 1G9 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.

The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
