pH dependent PTX retention after incubation of SKOV-3 cells with PTX loaded NPs or free PTX at pH 7.4 or 6. Cells were incubated with the NPs for 2.5 hours at either pH and separated from NPs, and analyzed for PTX content. Data are expressed as averages and standard deviations of 4–8 wells of cells treated with two independently and identically prepared batches of NPs. *: p < 0.05, by two-tailed t-test.
