Recognizes the CD28 co-stimulatory receptor, a ligand of CD80 (B7-1) and CD86 (B7-2). CD28 is important for transmitting co-stimulatory signals for optimal T-cell activation. Present on most thymocytes, CD4+, CD8+ T-cells. The 37.51 antibody augments proliferation and IL-2 production by activated T-cells.
