This antibody recognizes the same epitope as clone 37.51.
This monoclonal antibody reacts with mouse CD28, a 45 kDa costimulatory receptor and a member of the lg superfamily, CD28 is expressed by thymocytes, most peripheral T cells, and NK cells. CD28 is a receptor for CD80 (B7-1) and CD86 (B7-2). Signaling through CD28 augments lL-2 and IL-2 receptor expression as well as cytotoxicity of CD3-activated T cells. This antibody has been shown to stimulate the proliferation and cytokine production by activated T and NK cells and provide a costimulatory signal for CTL induction.
