FIG. 6.

Effect of SM on late gene expression. SM-KO cells were transfected with Z plus empty vector (Z), Z plus BALF5/BSLF1 (Z/PP), or Z plus SM (Z/SM). Cells were fixed and stained with anti-gp350 monoclonal antibody and Alexa Fluor-labeled secondary antibody prior to fluorescence microscopy (shown in the right panels and labeled gp350). All SM-KO cells are GFP positive, and corresponding GFP images are shown in the left panels (GFP). Expression of gp350 was only detected in the Z-plus-SM-transfected cells.
