FIG. 5.

Analysis of apoptosis-specific DNA fragmentation in mock-infected and persistently HAV/7-infected FRhK-4 cells after transfection with poly(IC). Cytoplasmic DNA extracts were prepared 12 h after transfection with 20 μg of poly(IC)/ml [poly(IC)+]. After treatment with RNase A, the samples were analyzed on a 1.6% agarose gel. As controls, the cells were mock transfected [poly(IC)−; DEAE-dextran+] and not transfected [poly(IC)−; DEAE-dextran−]. Shown are the data of an experiment representative for a series of three, each including two replicates.
