Fig. 8. Phagosome-phagosome fusion rates are increased in cells expressing RabD^Q67L. Control (left panels), RabD^Q67L (middle panels) and RabD^Q67L treated with 20 µM LY294002 (right panels) cells were incubated with FITC bacteria for 10 minutes, washed and chased for 60 minutes. Cells were gently fixed and phase contrast and fluorescent images were taken using a fluorescence microscope. Bar, 3 µm.
