Description: The 24F monoclonal antibody reacts with rat CD86, an ~90 kDa surface receptor, also known as B7-2. CD86 and CD80 are members of the B7 family of costimulatory molecules. CD86 is expressed by germinal center B cells and at low levels on macrophages, dendritic cells and non-lymphoid cells in the thymus. Its expression is upregulated on B cells through a variety of surface stimuli including LPS. In addition to CD80 (B7-1), CD86 is a counter-receptor for the T cell surface molecules CD28 and CD152 (CTLA-4). The interaction of CD86 with its ligands plays a critical role in T-B crosstalk, T cell costimulation, autoantibody production and Th2-mediated Ig production. The kinetics of upregulation of CD86 upon stimulation supports its major contribution during the primary phase of an immune response.
Applications Reported: The 24F antibody has been reported for use in flow cytometric analysis.
Applications Tested: The 24F antibody has been tested by flow cytometric analysis of resting and activated rat splenocytes. This can be used at less than or equal to 0.25 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.

CD86 is one of two ligands (the other CD80) for CTLA4 and CD28. CD86 acts as costimulatory molecule in eliciting T-cell help during antigen presentation. Antigen presentation in the absence of sufficient costimulation involving CD86/CD80 can induce tolerance. CD80 appears to play a role distinct from CD80 in T helper cell differentiation.
