FIG. 5.

Agarose gel electrophoresis of low-molecular-weight DNA extracted from infected HEp-2 cells. The DNAs were separated in a 1.5% agarose gel and stained with ethidium bromide after extraction at 6, 9, 12, 15, and 24 h p.i. from vBSΔ27 (Δ)- or KOS1.1 (K)-infected HEp-2 cells and at 24 h p.i. from mock (M)-infected HEp-2 cells as described in Materials and Methods. The locations of 1.2- and 0.7-kb markers are shown in the left margin.
