FIG. 5.

Effect of BFA on the distribution of UL51 protein and β-COP. ST51 cells were pretreated with either AlF (g to i) or DOG-Az (j to l) for 10 min at 37°C and mock treated (a to c) or treated with BFA (5 μg/ml) (d to l) for 30 min at 37°C. Cells were then fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. The cells were double stained and fluorescence images were obtained as described in the legend to Fig. 4.
