[CUSABIO]: CD20, WHY IS IT SUCH POPULAR IN ANTIBODY DRUG DEVELOPMENT?

CD20 is a cell surface tetraspan receptor expressed exclusively on B-lymphocytes, which are differentiated from pluripotent stem cells in the bone marrow and develop through the pro-B, pre-B, immature B and mature B stages. CD20 is present in the Pro-B to mature B cell stages, but is not expressed on haematopoietic stem cells, progenitor B cells or mature plasma cells.
