Figure 4

Fluorescence intensity of B16-F10 and M109 cells incubated with fluorescently-labeled PD complexes, prepared with CLPEI* and DS* in the DS/CLPEI ratios indicated in the x-axis at a concentration equivalent to CLPEI 3 µg/mL, for 6 h. Fluorescence intensity of (a) CLPEI* and (b) DS* in the cells was measured with flow cytometry and expressed as the geometric mean. MFI: Mean fluorescence intensity. Data are expressed as averages and standard deviations of 3 independently and identically performed tests.
