FIG. 3.
After 12 passages of the various drug treatments, all drugs were either left on (A) or removed (B) or cells continued to be cultured in the presence of an iminosugar only for a further 10 passages (30 days) (C). The numbers of viral RNA copies at P22 were measured by real-time RT-PCR and are shown as a percentage of the numbers of copies for the non-drug-treated BVDV-infected control. The data presented are from two independent experiments (experiments E1 and E2) in which the no-drug control contained 1.13 × 107 and 4.6 ×106 RNA copies/ml, respectively.
