Vβ 6 T-Cell Receptor Rat anti-Mouse, Brilliant Violet 711, Clone: RR4-7, BD Optibuild™

Description

• The RR4-7 antibody specifically reacts with the V β 6 T-Cell Receptor (TCR) of mice having the a ( e.g., C57BR, C57L, SJL) and b ( e.g., A, BALB/c, CBA/Ca, C3H/He, C57BL, DBA/1) haplotypes of the Tcrb gene complex
• The Tcrb-V6 gene locus is deleted in mice having the c ( e.g., RIII) haplotype
• V β 6 TCR-bearing T lymphocytes are clonally eliminated in mice expressing superantigen encoded by Mtv-7 ( Mls-1[a], Mls[a] ) endogenous provirus ( e.g., AKR, CBA/J, C58, DBA/2, NZB), or Mtv -43 endogenous provirus ( e.g., MA/MyJ)
• Exogenous MMTV-SW, as well as endogenous Mtv -44-encoded superantigen ( e.g., NZW), also causes incomplete elimination of V β 6 TCR-expressing T cells
• Plate-bound RR4-7 antibody activates V β 6 TCR-bearing T cells, soluble RR4-7 mAb blocks in vitro proliferation and cytolytic activities of V β 6 TCR-bearing T-cell clones, and injection of the antibody results in in vivo depletion of V β 6 TCR-bearing T cells
• 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.
