ICOS is a T cell specific activation molecule and a third member of the CD28\/CTLA-4 family. A dimer 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, is thought to play a protective role in inflammatory autoimmune diseases and be involved in the development of Th2 cells. C398.4A is reported to display strong costimulation of proliferation of T cell clones, intermediate costimulation on activated T cells, and weak costimulation on fresh resting T cells. It is a good costimulator of IL-10 production especially from pre-activated cells that express high level of H4\/ICOS. The epitope recognized by C398.4A is different from that bound by the ICOSL (i.e., C398.4A does not block binding of ICOSL).\u003c\/p\u003e\u003cp\u003eApplications Reported: This C398.4A antibody has been reported for use in flow cytometric analysis.\u003c\/p\u003e\u003cp\u003eApplications Tested: This C398.4A antibody has been tested by flow cytometric analysis of stimulated 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.\u003c\/p\u003e\u003cp\u003eAPC-eFluor® 780 emits at 780 nm and is excited with the Red laser (633 nm).
