CD20 is a transmembrane protein of the tetra-spanin family expressed on the surface of B-cells and has been found on B-cells from peripheral blood as well as lymphoid tissues. CD20 expression persists from the early pre-B cell stage until the plasma cell differentiation stage. Conversely, it is not found on hematopoietic stem cells, pro-B cells, differentiated plasma cells or non-lymphoid tissues.
