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.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimal conditions that minimize unconjugated dye and antibody.
1. This antibody was developed for use in flow cytometry.
2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
3. Researchers should determine the optimal concentration of this reagent for their individual applications.
4. An isotype control should be used at the same concentration as the antibody of interest.
5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
