The T cell-specific receptor CD28 is an important regulator of the immune system. The ligation of CD28 and its ligands CD80/CD86 on the APC provides a critical costimulatory signal alongside T cell receptor (TCR) for T cell activation. The costimulatory signal can also be delivered by the interaction between CD28 and its agonist antibody.
Recombinant monoclonal antibody recognizing human CD28. This antibody binds to CD28 on T cells and promotes T cell response. Not tested in other species.
T-Cell-Specific Surface Glycoprotein, TP44
