Penetration kinetics. The rates of entry of PrV-1112 into RK13 (▴), CHO (○), and HveC-expressing CHO cells (X) were determined by low-pH inactivation of extracellular virus. The percentage of infectious events (plaques, foci, or infected single cells [Fig. 1]) at a given time point calculated in comparison with PBS-treated control plates is shown. Data are averages of three independent experiments. Vertical lines indicate standard deviations.
