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.
