Figure 7: Effects of surfactants on uptake of paclitaxel and docetaxel in AH130 cells. Cells were treated with 3 μg/mL of docetaxel (DOC) or paclitaxel (PAC) dissolved with 0.125% ethanol (0) or the indicated concentrations of crEL or PS-80 (PS) for 30 min. The data at 0.0125% concentration of these surfactants are taken from . Each column with bar represents the mean ± SD of at least three experiments performed in triplicate. *,**Significantly different from docetaxel at and 0.01, respectively.
