Expression of CD20 on the surface of Raji cells. (a, b, c) Cell surface expression of CD20 was visualized using an inverted fluorescent microscope and a FITC-labelled anti-CD20 monoclonal antibody. (d) Cell surface expression of CD20 was quantified using flow cytometry and a FITC-labelled anti-CD20 monoclonal antibody.
