Infection of Huh-7 cells and HepG2 cells by the HDAdJFH1 virus. (a). A diagram depicting the genetic makeup of HDAdJFH1. The transcriptional expression of the JFH1 RNA genome is under the control of the CMV promoter and the HDV ribozyme. The GFP expression cassette is under the control of a second CMV promoter and contains an SV40 polyA tail. (b). GFP expression in HDAdJFH1-infected Huh-7 cells and HepG2 cells on day 3 p.i. Magnification, ×10 (b).
