Hamster anti Mouse CD278 antibody, clone C398.4A recognizes CD278, also known as Inducible T cell costimulator or ICOS, a CD28-superfamily costimulatory molecule. It is expressed on activated T cells and resting memory T cells. It enhances all the basic T cell responses to a foreign antigen, namely proliferation, secretion of lymphokines and up-regulation of molecules that mediate cell-cell interaction. It is essential for the efficient interaction between B and T cells and is involved in antibody responses to T cell dependent antigens. It up-regulates the synthesis of interleukin-10, but not interleukin-2 and prevents the apoptosis of pre-activated T cells. Hamster anti Mouse CD278 antibody, clone C398.4A has been reported to costimulate T cell activation and proliferation in vitro.
