PD sensitivity of different cell lines. Cells were treated with PD complexes, prepared with CLPEI and DS at the DS/CLPEI ratios and CLPEI concentrations indicated in the x-axis, for 6 h, followed by additional incubation for 18 or 42 h in fresh medium. The cell viability was tested with the MTT assay or CellTiter-Glo luminescent cell viability assay (B16-F10 cells). Top: Cells sensitive to PD complex at a specific DS/CLPEI ratio (PD-sensitive cells). Bottom: Cells insensitive to PD complexes at any ratio of DS/CLPEI (PD-insensitive cells).
