Localization of SWNT-PL-PEG in subcellular components of different cells. A. Localization of SWNT-PL-PEG in different subcellular components of HeLa cells. Cells (5×104 per well) transfected with DsRed-ER, DsRed-Golgi, CFP-lamp, or stained with MitoTracker were incubated with SWNT-PL-PEG-FITC (2.5 μg/ml) for 30 minutes. Confocal images of the cells show that SWNT-PL-PEG-FITC is localized in the mitochondria, but not in ER, Golgi, or lysosomes. B. Mitochondrial localization of SWNT-PL-PEG in different cells. Cells (ASTC-a-1, MCF 7, COS 7, EVC304) were stained by MitoTracker and incubated with SWNT-PL-PEG-FITC for 30 minutes. Confocal images of the cells show consistent mitochondrial localization of SWNT-PL-PEG-FITC in all cells. C. Lysosomal localization of SWNT-PL-PEG in macrophages. Cells transfected with CFP-lamp and stained with MitoTracker were incubated with SWNTs-PL-PEG-FITC for 30 minutes. Confocal images of the cells show that SWNT-PL-PEG-FITC is mainly localized in the lysosome.
