Invitrogen CD28 Monoclonal Antibody (CD28.2), Functional Grade, 500 µg, eBioscience™

Invitrogen CD28 Monoclonal Antibody (CD28.2), Functional Grade, 500 µg, eBioscience™

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: Functional Assay (FN), T-Cell Activation (TCA) and In vitro Assay (IV).
