FIG. 5.
Digitally scanned electron micrograph of wild-type (WT) virus-infected Vero cells harvested and fixed late in infection. Thin sections were probed with US3 protein-specific rabbit polyclonal antisera. Bound antibody is indicated with arrowheads labeled pUS3. The nucleus is indicated, and the locations of the INM and ONM are indicated by double arrowheads in panel A. In addition to the subcellular structures labeled in panel A, the location of the cytoplasm is indicated in panel B. In panel C, the cytoplasm and plasma membrane (PM) are designated and extracellular virions labeled with pUS3 are shown. Original magnification of panels A to C, ×45,000.
