CD28 antibodies, human

CD28 antibodies, human

Clone: REA612 | Dilution: 1:50
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.

T44, Tp44
