Vβ 5.1, 5.2 T-Cell Receptor Mouse anti-Mouse, Brilliant Violet 605, Clone: MR9-4, BD Optibuild™

Description

• The MR9-4 monoclonal antibody specifically recognizes the V β 5.1 and V β 5.2 T-cell Receptors of strains having the b haplotype (e.g., C57BL) of the Tcrb gene complex
• These gene loci are deleted in mice having the a (e.g., C57BR, C57L, SJL, SWR) or c (e.g., RIII) Tcrb haplotype
• V β 5.1 and 5.2 TCR-bearing T lymphocytes are clonally eliminated, either completely or partially, in mice expressing I-E and superantigens encoded by the Mtv-1 (Mls-4a, Mlsc), Mtv-3 (Mlsc), Mtv-8 (Mlsf), Mtv-9 (Etc-1, Mlsf), Mtv-11 (Mlsf), Mtv-13 (Mls-2a, Mlsc), Mtv-27, Mtv44, and/or Mtv-MAI endogenous provirus (e.g., A, AKR, BALB/c, C3H/He, C58, CBA/Ca, CBA/J, DBA/2, NZB, NZW)
• Activation of V β 5 TCR-expressing T cells by this determinant is dependent upon presentation by I-E
• Plate-bound MR9-4 antibody activates V β 5.1 or 5.2 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.
