Product Specific Information
Description:
The 37.51 monoclonal antibody reacts with the mouse CD28 molecule, a 45 kDa homodimer expressed by thymocytes, mature T cells, and NK cells. CD28 is a ligand for CD80 (B7-1) and CD86 (B7-2) and is a potent costimulator of T cells. Signaling through CD28 augments IL-2 and IL-2 receptor expression as well as cytotoxicity of CD3-activated T cells.
Applications Reported:
The 37.51 antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and immunohistochemical staining. It has also been reported in costimulation of T cells in vitro and in vivo.
(Use Functional Grade purified 37.51, Product #16-0281 for functional assays.)
Applications Tested:
Tested by flow cytometric analysis of mouse splenocytes. Recommended ≤0.5 µg per test (100 µL final volume). Cell number should be empirically determined (10⁵–10⁸ cells/test). Antibody titration is recommended for optimal performance.
Note:
Increased incubation times (30–45 minutes) may enhance staining quality.
Purity: >90% (SDS-PAGE)
Aggregation: <10% (HPLC)
Filtration: 0.2 µm post-manufacturing filtered
Target Information
CD28 antigen is a 44 kDa disulfide-linked homodimeric T cell-specific surface glycoprotein of the immunoglobulin superfamily. It is constitutively expressed on most peripheral blood T lymphocytes and acts as a critical costimulatory receptor by binding CD80 and CD86 on antigen-presenting cells. CD28 prevents T cells from entering an anergic state or undergoing premature apoptosis. In mice, CD28 is expressed on all CD4+ and CD8+ T cells in peripheral lymphoid organs and blood, with varying expression levels during thymocyte maturation.
Diseases associated with CD28 dysfunction include mycosis fungoides and Sezary’s disease.
