CD28 antibodies, human

CD28 antibodies, human

Clone: 15E8 | Dilution: 1:11
The CD28 antibody recognizes the human CD28 antigen, a type I transmembrane protein, which is highly expressed on CD3
thymocytes, most peripheral thymocytes and plasma cells. Binding of CD28 to its ligands CD80 or CD86 costimulates T cell effector function and T cell–dependent antibody production
in vitro
in vivo
. In the presence of antibodies directed against CD2 and CD3, CD28 antibodies stimulate T cell proliferation and cytokine production.

Alternative names

Tp44, T44
