Description
- 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
- Applications Tested: The 37.51 antibody has been tested by flow cytometric analysis of mouse splenocytes
- This can be used at less than or equal to 0.5 μg per test
- A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
- Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
- It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest
- Note: It has been observed that increased incubations times (30-45 minutes) with the CD28 antibody can enhance the staining obtained
- Filtration: 0.2 μm post-manufacturing filtered
- CD28 antigen is a 44 kDa disulfide linked homodimeric T cell specific surface glycoprotein
- CD28 is a cell adhesion molecule of the immunoglobulin superfamily which is constitutively expressed on most peripheral blood T lymphocytes
- Moreover, CD28 is the critical T cell costimulatory receptor that provides the cell the important second activation signal by binding CD80 and CD86 which are expressed by antigen presenting cells
- In addition to its co-stimulation role, CD28 functions by preventing T cells from entering an anergic-hyporesponsive state or from undergoing premature apoptotic cell death
- In murine peripheral lymphoid organs and in the blood, all CD4+ and CD8+ T cells express CD28
- In the thymus, CD28 expression is highest on immature CD3-, CD8+ and CD4+8+ cells, and on CD4-8- cells that express alpha/beta and gamma/delta TCR
- The level of CD28 on mature CD4+ and CD8+ alpha/beta TCR+ thymocytes is two- to fourfold lower than on the immature cells
- Diseases associated with CD28 dysfunction include mycosis fungiodes and Sezary's Disease.
