CD28 Antibody, anti-human, APC-Vio® 770, REAfinity™

01MT04943

Clone REA612 recognizes the human CD28 antigen, a type I transmembrane protein, which is highly expressed on CD3+ thymocytes, most peripheral thymocytes, and plasma cells but not in less mature B cells. Binding of CD28 to its ligands CD80 or CD86 costimulates T cell effector function and T cell–dependent antibody production in vitro and in vivo. In the presence of antibodies directed against CD2 and CD3, CD28 antibodies stimulate T cell proliferation and cytokine production.Additional information: Clone REA612 displays negligible binding to Fc receptors.
