(a) PTX retention normalized with total protein content. Micro BCA assay was performed to determine the total protein content in the cell lysate as an estimate of cell population. The PTX to protein ratio reflects PTX retained by each cell. (b) Cytotoxicity of PPT and PNC (equivalent to 7 μM PTX) to SKOV3 cells after 3h of direct exposure followed by incubation in drug-free medium. (c) Fraction of cells affected by unit amount of PTX. Data are expressed as averages and standard deviations of three measurements of a representative batch. *: p<0.05 by t-test.
