Figure 7
Confocal microscopy subcellular localization of Co 3 O 4 particles. Cells were stained for Golgi marker GM130 (red) (A), early endosome marker EEA1 (red) (B), or lysosome marker LysoTracker (red) (C), as described in the materials and methods section, before being analyzed by confocal microscopy. Yellow staining in the merged images indicates co-localization of the cobalt oxide particles (green) with the fluorescent label (red). Scale bar, 10 μm.
