Description: The 7E.17G9 monoclonal antibody reacts with mouse ICOS (Inducible COStimulatory molecule), a T cell specific molecule and a third member of the CD28/CTLA-4 family. A homodimer of 47-57 kDa, ICOS is expressed on activated T cells, has potent costimulatory activity for T cell activation and proliferation and is required for humoral immune response. ICOS binds to its ligand on activated APC including B cells called B7h/B7RP-1 and is thought to play a protective role in inflammatory autoimmune diseases. ICOS may be involved in the development of Th2 cells.
Applications Reported: 7E.17G9 has been reported for use in flow cytometric analysis and for inhibition of ligand binding in functional assays (please use Functional Grade purified, cat. 16-9942).
Applications Tested: The 7E.17G9 antibody has been tested by flow cytometric analysis of unstimulated and Con A activated (3 day) mouse splenocytes and can be used at less than or equal to 1 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.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
CD278 belongs to the CD28 and CTLA-4 cell-surface receptor family and is highly expressed in activated T-cells. It is essential both for efficient interaction between T and B-cells and for normal antibody responses to T-cell dependent antigens. It enhances all basic T-cell responses to a foreign antigen, namely proliferation, secretion of lymphokines, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B-cells.
