Plaque morphologies of EGFP viruses on murine 17 Cl 1 cell monolayers. Plaques of the SA59, Y162F and Y162A-EGFP viruses were visualized at 72 h post-inoculation (p.i.) by neutral red staining (neutral red) or immunoperoxidase labeling of viral nucleocapsid protein (N antigen) in cell monolayers. Plaques formed by the Y162A-EGFP virus are indicated by black arrows.
