FIG. 5.

Na increases the ability of R to activate EBV replication in 293 R-KO cells. Supernatants from the cells transfected for Fig. 3B were harvested, and the amounts of infectious virus present were quantitated as described in Materials and Methods. x axis labels represent the transfected plasmids and y axis labels represent the numbers of infectious units per milliliter of supernatant harvested. The data shown represent the results of two independent experiments.
