Vβ 8.1, 8.2 TCR Mouse anti-Mouse, Brilliant Violet 605, Clone: MR5-2, BD Optibuild™

Description

• The MR5-2 antibody reacts with the V β 8.1 and V β 8.2 T-cell Receptors (TCR), but not the V β 8.3 TCR, of mice having the b haplotype ( e.g ., A, AKR, BALB/c, CBA/Ca, CBA/J, C3H/He, C57BL, C58, DBA/1, DBA/2) of the Tcrb gene complex
• The Tcrb-V8 subfamily gene loci are deleted in mice having the a ( e.g ., C57BR, C57L, SJL, SWR) or c ( e.g., RIII) haplotype
• V β 8.1 TCR-bearing T lymphocytes are clonally eliminated in mice expressing superantigen encoded by the Mtv-7 (Mls-1a, Mlsa), provirus ( e.g., AKR, CBA/J, C58, DBA/2), and activation or elimination of V β 8.1 TCR-expressing T cells by this determinant is partially dependent upon presentation by I-E
• Mtv-43 (e.g., MA/MyJ), Mtv-44 (e.g., NZW), and/or exogenous MMTV-SW superantigens also cause incomplete elimination of V β 8.1 TCR-bearing T cells
• In addition to expression on conventional T lymphocytes, V β 8.2 is the predominant β chain of the TCR on NK-T cells
• Staphylococcal enterotoxin B, in association with antigen presenting cells expressing I-A and/or I-E, stimulates lymphocytes bearing V β 8 TCR and selectively eliminates those T cells in vivo
• Plate-bound MR5-2 antibody activates V β 8.1 or 8.2 TCR-bearing T lymphocytes
• 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.
