Figure 2.
Protein expression and localization of MDV and REV examined by confocal laser scanning microscope (CLSM). The proteins of MDV and REV were co-localized in cytoplasm (arrowhead). The coinfected cells showed more cytopathy (CPE) (star) than single-infected cells. Samples stained with pp38 or gp90 antibodies as well as Cy3-labeled goat anti-rabbit IgG (for MDV) (red) or FITC-labeled goat anti-mouse IgG (for REV) (green) antibody in the assay. The areas of colocalization are shown in yellow. Cell nuclei (blue) were stained with DAPI. MDV, Marek's disease virus; REV, reticuloendotheliosis virus; CLSM, confocal laser scanning microscope; CPE, cytopathic effect; FITC, fluorescein isothiocyanate.
