FIG. 5.
Replication kinetics of PA-457-resistant viruses. Jurkat T cells were transfected with WT pNL4-3 or derivatives containing the indicated mutations. Cultures were maintained either without PA-457 or with 50 ng/ml or 1.0 μg/ml PA-457. Cells were split every 2 days, and supernatants were reserved at each time point for RT analysis.
