Figure S3. Non-GPI-binding B cells in VH147 tg mice are phenotypically similar to tg neg B cells. Spleen and LN cells from VH147 tg or tg neg mice were stained with the phenotypic (A) or activation (B) markers described in Fig. 1 and analyzed by flow cytometry. Histograms show surface marker expression for splenic or LN B220+GPI- cells from VH147 tg mice (open histograms) overlaid tg neg B cells (closed histograms). n = 8 mice of each genotype.
