TIGIT Mouse anti-Mouse, Brilliant Violet 711, Clone: 1G9, BD Optibuild™

Description

• 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™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes
• This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405nm and an acceptor dye with an Em Max at 711nm
• BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor™ 700-like dyes (eg, 712/20nm filter)
• Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors
• However, the spillover can be corrected through compensation as with any other dye combination
• BV711 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 711 nm
• This dye offers a very bright choice for the violet laser
• Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors
• BV711 will also have moderate spillover into the BD Horizon Brilliant™ Violet 786 detector.
