Figure 1: Induction of cell death by MβCD or rituximab. (A) MEC1 cells incubated in the presence (+) or absence (-) of 10 μg/mL of rituximab for 24 h at 37°C and analyzed by flow cytometry. (B) MEC1 cells starved for fetal calf serum for 1 h then incubated in the presence (+) or absence (-) of 1 mM MβCD for 1 h at 37°C. The figures are representative of three independent experiments.
