pH-dependent intracellular accumulation of VP. a Dose-dependent intracellular accumulation of VP was analysed by fluorimetry in HCT116 and AAHCT116 cells and normalised to protein content. b HCT116 and AA-HCT116 cells were treated with VP for 30 min and analysed by confocal microscopy. Scale bar 10 μm. c Intracellular accumulation of VP was analysed by fluorimetry in HCT116 cells transiently exposed to medium at pH 7.4 or pH 6.8 for 4 h. *P<0.05
