Surfactin co-located with mitochondria in macrophages.
Raw 264.7 cells were incubated with NHS-Rhodamine B-labeled SFN and Mito-Tracker, then observed by Confocal microscopy (Magnification is 63×). NHS-Rhodamine B-labeled SFN (red fluorescence) co-located with the mitochondria-specific dye of Mito-Tracker (green fluorescence) in the cytoplasm of macrophages (directed by white arrows).
