CD86 Rat anti-Mouse, Brilliant Violet 650, Clone: GL1, BD

Description

• The GL1 antibody has been reported to react with the B7-2 (CD86) costimulatory molecule expressed on a broad spectrum of leukocytes, including B lymphocytes, T lymphocytes, thioglycollate-induced peritoneal macrophages, dendritic cells and astrocytes
• CD86 is expressed at low levels by freshly explanted peripheral B and T cells, and its expression is substantially increased by a variety of T cell- and B cell-specific stimuli with a peak expression after 18-42 hours of culture
• In contrast to most naive CD4+ T cells, memory CD4+ T cells express B7-2, both at the mRNA and protein level
• CD86, a ligand for CD28 and CD152 (CTLA-4), is one of the accessory molecules that plays an important role in T cell-B cell costimulatory interactions
• It has been shown to be involved in immunoglobulin class-switching and triggering of mouse NK cell-mediated cytotoxicity
• CD80 (B7-1) is an alternate ligand for CD28 and CD152 (CTLA-4)
• GL1 antibody reportedly blocks MLR and stimulation of T cells by natural antigen-presenting cells
• In addition, a mixture of anti-B7-1 and anti B7-2 (GL1) mAbs reportedly inhibits the in vitro interaction of CTLA-4 with its ligand and the in vivo priming of cytotoxic T lymphocytes
• The antibody was conjugated to BD Horizon BV650 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 405-nm and an acceptor dye with an Em Max at 650-nm
• BD Horizon BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter)
• Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor™ 700 detectors
• However, the spillover can be corrected through compensation as with any other dye combination.
