FIG. 3.

Analysis of FMDV interaction with clathrin or caveolin-1 in MCF-10A cells. Cells were infected with type O₁Campos (a to f), O₁C3056R-KGE (g to l), and O₁C3056R (m to r) or were mock infected (s to x) at 4°C as described in Materials and Methods. Cells were fixed and probed, as described in Materials and Methods, for viral proteins (red), clathrin (green), or caveolin-1 (green) at 15 min after the temperature was shifted to 37°C.
