FIG. 7.

Determination of replicon RNA levels in selected cell lines, 24-1, 25-1, and 25-2, each harboring the adapted replicon 5.1. Cells were harvested at given times after being seeded, and HCV RNA was analyzed by Northern blotting as described in the legend to Fig. 3. A summary of the data, including analogous quantifications with cell lines harboring other replicon RNAs, is given in Table 2. β-act., β-actin.
