The mouse monoclonal antibody clone CD28.2 binds to human CD28, a 44 kDa type I surface glycoprotein that acts as a co-stimulatory receptor in support of the T cell receptor (TCR). CD28 is a homodimer with specificity for two known ligands, B7-1 (CD80) and B7-2 (CD86), which are expressed on activated B cells and antigen-presenting cells. These ligands trigger CD28 signaling in concert with TCR activation to drive T cell proliferation, induce high-level expression of IL-2, impart resistance to apoptosis, and enhance T cell cytotoxicity. The co-stimulatory signaling between the B7 ligands and CD28 provides crucial communication between T cells and B cells or APCs to coordinate the adaptive immune response. Other members of the CD28 family of receptors include CTLA-4 (CD152), PD-1 (CD279), ICOS and BTLA.

RECOMMENDED USAGE

Flow cytometry: The suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL.
