Colocalization of Lipo-VP and TPP-Lipo-VP with the mitochondria and lysosomes. a–c Representative confocal laser scanning microscopy images of VP (pseudo green colour to distinguish between VP and trackers), Mitotracker Red (red channel) and LysoTracker (red channel) in HCT116 cells after incubation with Lipo-VP (250 µM) and TPP-Lipo-VP (250 µM). Merged images of green and red channels indicated colocalization level of the liposomes and mitochondria (or lysosomes). Scale bar is 20 µm
