Vβ 11 T-Cell Receptor Rat anti-Mouse, Brilliant Violet 605, Clone: RR3-15, BD Optibuild™

Description

The RR3-15 antibody reacts with the Vβ11 T-Cell Receptor (TCR) of mice having the b haplotype (e.g., A, C57BL, C58, DBA/1) of the Tcrb gene complex. The Tcrb-V11 gene locus is deleted in mice having the a (e.g., C57BR, C57L, SJL, SWR) and c (e.g., RIII) haplotypes. VβTCR-bearing T lymphocytes are clonally eliminated in mice expressing I-E and superantigens encoded by Mtv-9 (Etc-1, Mls[f], Dvb11.2) and/or Mtv-11 (Mls[f], Dvb 11.2) proviruses (e.g., AKR, BALB/c, CBA/J, C3H, DBA/2), and they are incompletely eliminated in mice expressing I-E and Mtv-8 (Mls[f], Dvb 11.1) superantigen (e.g., A). Activation of Vβ11 TCR-expressing T cells by these determinants is dependent upon presentation by I-E. The bacterial superantigen Staphylococcal enterotoxin A (SEA) also interacts with Vβ11 TCR, and in vivo exposure to SEA causes activation and subsequent deletion of VβTCR-expressing lymphocytes. Plate-bound RR3-15 antibody activates Vβ11 TCR-bearing T cells.

This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407nm and Em Max of 602nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20nm filter set. BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers. BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser. BV605 is a tandem fluorochrome that combines BD Horizon BV421 and Cy™3.5. These conjugates are very bright, exhibiting similar brightness to equivalent PE conjugates. Due to the excitation of Cy3.5 by the green (532nm) and yellow-green (561nm) lasers, there will be significant spillover of the BD Horizon BV605 signal into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers.
