CD28 Mouse anti-Human, APC, Clone: CD28.2, BD

Mouse Monoclonal Antibody

Supplier:  BD Biosciences 559770

Catalog No. BDB559770

Description

Recognizes a 44kDa homodimeric transmembrane glycoprotein present on most mature T cells, thymocytes and plasma cells. CD28 is the ligand for CD80 and plays a very important role in T cell-B cell interaction. It has been suggested that CD28 initiates and regulates a separate and distinct signal transduction pathway from those stimulated by the TCR complex. Additionally, it has been reported that CD28 antibody clones vary in their ability to stimulate T cells to produce IL-2 and increase intracellular Ca2+ concentration. This finding suggests the existence of functionally distinct subregions on the CD28 molecule. CD28.2 has been demonstrated to bind to the same molecule as clone L293, another CD28 mAb, and has been reported to induce Ca2+ influx in Jurkat T cells.
