FIG. 3.
CMV rescues VVΔE3L late gene expression even in the presence of ganciclovir. Triplicate wells of HF were mock infected (−) or infected with CMV (+). At 1 hpi, cells were fed with medium containing (+, black bars) or lacking (−, shaded bars) 30 μM ganciclovir. At 24 hpi, the cells were mock infected (−) or infected with VVΔE3L (+), and β-Gal activity (+SD) was measured 24 h later.
