Description

The CD28.2 monoclonal antibody reacts with the human CD28 molecule, a 44 kDa homodimer expressed by thymocytes, mature T cells and plasma cells. CD28 is a ligand for CD80 (B7-1) and CD86 (B7-2) and is a potent co-stimulator of T cells. Signaling through CD28 augments IL-2 and IL-2 receptor expression as well as cytotoxicity of CD3-activated T cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The CD28.2 antibody has been reported for use in flow cytometric analysis.

Applications Tested

The CD28.2 antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 20 μl (0.25 μg) per 100μl blood (or per 1 million cells in 100 μl total staining volume).
