The majority of lymphomas derived from Eμ-myc/E6AP^+/− mice display a mature sIg⁺ B cell immunophenotype. (A) Representative dot plots of the most common immunophenotypic profiles obtained by flow cytometric analyses of Eμ-myc/E6AP^+/− and control (E6AP^+/+) Eμ-myc lymphomas stained with the antibodies to B220, IgM, and IgD. (B) Summary of immunophenotypic analysis of Eμ-myc/E6AP^+/− and control (E6AP^+/+) Eμ-myc lymphomas.
