Expression of human and murine CD20 on plasma cells. Each population of cells from 7-week-old hCD20/K/g7 vs. hCD20/g7 mice or K/BxN vs. BxN mice was defined as in Fig. 3 [GPI intracellular staining (G)]. The number in each histogram represents the MFI of all cells or gated cells when the gate is indicated by a bar. For hCD20 expression, K/g7 mice were used as negative control and indicated by the light dotted line in each histogram. Lymphocytes were excluded from the G^-CD138⁺ population by forward-scatter and side-scatter.
