FIG. 7.

FMDV entry into SW480-αvβ6 cells. SW480-αvβ6 cells, prepared on coverslips, were incubated with FMDV at 4°C for 1 h, washed to remove excess unbound virus, and shifted to 37°C. Virus that had entered the cells was detected using the confocal microscope. Shown is labeling (in white) for FMDV after incubation at 37°C for (a) 5, (b) 10, (c) 15, and (d) 30 min. The nuclei were stained with DAPI and are shown as grey. Bars, 5 μm.
