FIG. 9.

In vivo integration of viral mutants. QT6 cells were infected with equal amounts of freshly harvested WT and mutant viruses (as estimated by RT units). At different time points, whole-cell DNA was extracted and loaded (undigested) onto agarose gels. The gels were blotted and probed with a 900-bp gag fragment, corresponding to bases 1775 to 2683 of pATV8.
