CD134 Rat anti-Mouse, Brilliant Violet 711, Clone: OX-86, BD Optibuild™

Description

• The OX-86 monoclonal antibody specifically binds to the OX-40 antigen (CD134), also known as OX-40L receptor
• CD134 is a 50-kDa type-I membrane glycoprotein that belongs to the NGFR/TNFR superfamily
• Mouse CD134 is expressed on activated CD4+ and CD8+ T lymphocytes and has been shown to be the sole receptor for the OX-40 Ligand (OX-40L)
• In the brains of mice with actively induced experimental allergic encephalomyelitis, the expression of CD134 on CD4+ T lymphocytes correlates with disease progression
• The OX-40/OX-40L system supplies a costimulatory signal for T-cell proliferation and B-cell proliferation and differentiation
• In addition, OX-40 antigen provides a costimulatory signal that induces T cells to proliferate in a CD28-independent manner
• In the intact animal, CD134 does not appear to be essential for many T-cell responses, but it seems to play a major role in the pathogenesis of some autoimmune diseases
• The OX-86 mAb stains both CD4+ and CD8+ activated T cells, and this expression pattern has been confirmed using OX-40L-Ig fusion protein
• CD134 was also detected, using OX-86 mAb, on B cells after stimulation with anti-IgM plus anti-CD40 mAb HM40-3 (Cat
• no
• 553721)
• OX-86 mAb does not block binding of OX-40L to OX-40, and it stimulates T-cell proliferation mildly
• The antibody was conjugated to BD Horizon™ BV711 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 711-nm
• BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor™ 700-like dyes (eg, 712/20-nm filter)
• Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors
• However, the spillover can be corrected through compensation as with any other dye combination.
