Background InformationB-lymphocyte antigen CD20 (UniProt P11836; also known as B-lymphocyte surface antigen B1, Bp35, CD20, Leukocyte surface antigen Leu-16, Membrane-spanning 4-domains subfamily A member 1) is encoded by the MS4A1 (also known as CD20) gene (Gene ID 931) in human. CD20 is a transmembrane, non-glycosylated protein expressed on B-cell precursors and mature B cells, but is lost following differentiation into plasma cells. In resting B cells, CD20 appears in a 33 kDa non-phosphorylated form. After mitogen stimulation, CD20 becomes heavily phosphorylated (35-37 kDa isoforms), and it is a dominant phosphoprotein in activated B cells and B-cell lines. The long N- and C-terminal ends of the protein are located on the cytoplasmic side of the membrane and only a minor portion of the protein is exposed on the cell surface. It is believed that CD20 plays a direct role in mediating B cells proliferation and differentiation by regulating the transmembrane conductive Ca2+ flux.

SpecificityOriginally reported to stain majority of prolymphocytic leukemia (B-PLL) and hairy-cell leukemia patients derived B cells (Catovsky, D., et al. (1981). Blood. 58(2):406-408.) and later reported to detect a 105 kDa protein species by immunoblotting (Zola, H., et al. (1987). Dis. Markers. 5(4):227-235.), clone FMC7 is now known to target a conformational epitope on the CD20 extracellular region. Clone FMC7 antigenicity is sensitive to levels of membrane cholesterol. Plamsa membrane cholesterol depletion by methyl-β-cyclodextrin treatment results in greatly reduced Ramos surface staining by clone FMC7 (Deans, J.P., and Polyak, M.J. (2008). Blood. 111(4):2492; author reply 2493-4; Polyak, M.J., et al. (2003). Leukemia. 17(7):1384-1389; Serke, S., et al. (2001). Cytometry. 46(2):98-104).
