Figure 1. Flow cytometry analyses of total and phosphorylated c-Abl levels in GC B and plasma cells.

Wildtype C57BL/6 mice were immunized with NP₃₈-CGG and examined 10 days later for intracellular levels of total and phosphorylated c-Abl (phopho-c-Abl) levels in gated (A) Fas⁺ CD38⁻B220⁺ GC (blue histogram) and Fas⁻CD38⁺ B220⁺ non-GC B cells (red histogram) and (B) B220^lowCD138⁺ PC (blue histogram) and B220^highCD138⁻ non-PC cells (red histogram). Staining with rabbit IgG antibody (gray histogram) was included as negative control. Data shown are representative of 3 independent experiments.
