Vβ 8 T-Cell Receptor Mouse anti-Mouse, Brilliant Violet 786, Clone: F23.1, BD Optibuild™
Mouse Monoclonal Antibody
Manufacturer: BD Biosciences 742381
The F23.1 antibody specifically reacts with the V β 8.1, V β 8.2, and V β 8.3 T-cell receptors (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 coded by 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 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 . Soluble and plate-bound F23.1 antibody activates V β 8 TCR-bearing T cells, soluble antibody blocks cytolysis mediated by V β 8 TCR-bearing cytotoxic T lymphocytes, and in vivo treatment of neonatal mice can arrest intrathymic maturation of V β 8 TCR-bearing T cells.The antibody was conjugated to BD Horizon™ BV786 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 786nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60nm filter). BV786 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 786 nm. BV786 offers a bright choice for the 6th detector off the violet laser.
