Fig. 9. Concanamycin A inhibits endocytosis in wild-type cells. Wild-type cells were treated (+) or not (-) for 20 min with 3 µmoll^-1 concanamycin A (dissolved in DMSO solution) before staining with FM 4-64, according to the standard procedure. Staining images were visualized at 50 min and 90 min. Left panels, FM 4-64 fluorescence; right panels, visible light images of the same cells.
