The 2H7 monoclonal antibody binds to human CD20, a 33-37 kDa, four-transmembrane phosphoprotein. CD20 is present on all stages of B cell development except for early pro-B cells or plasma cells to play a role in B-cell activation, proliferation and differentiation1. In some studies, CD20 is thought to act as a Ca2channel in the plasma membrane2. It is also present on a T cell subset at low levels as well as some follicular dendritic cells. The antibody was conjugated to a fluorophore and purified by chromatography.
