Dose-response curve of MoAb G28-5 antiapoptotic effect. B-CLL cells (1 × 106/mL) were incubated in 10% FCS-RPMI 1640 medium with fludarabine (0.8 μg/mL) in the presence of the indicated concentrations of MoAb G28-5 or control (HO5) antibody. After 3 days of cell culture, the apoptosis percentages were calculated.
