CD20, technical only
Use
CD20 is a transmembrane phosphoprotein expressed on B lineage cells. Expression is first noted on the pre-B-cell stage and continues throughout all stages of B-cell maturation until reaching pro-B cell and plasma cell stage. CD20 antigen is observed on some precursor B lymphoid neoplasms, mature B-cell neoplasms, nodular lymphocyte predominant Hodgkin lymphoma, and in a subset of classical Hodgkin lymphomas.
