The combined use of anti-CD33 mAb and etoposide displays a synergistic effect in binding of Annexin V. The surface binding of Annexin V to AML cells was measured after 20 h of culture with GM-CSF in the presence of anti-CD33 mAb (μg/ml), ETP (68 μM/ml), or ETP (34 μM/ml) used either alone or in combination. The experiment shown is representative of four independent experiments. Samples were stained with Annexin V FITC-conjugated mAb. Analysis was performed on PI-negative, viable cells.
