Fig. (2) PCR and restriction enzyme analysis of recombinant Ad5HVR7epB genome. Viral DNA extracted from Ad5HVR7epB infected HEK 293 cells was subjected to PCR (lane 1) and the PCR product was digested with AvrII (lane 2). The GeneRuler 1kb Plus DNA ladder (M) from Fermentas was used for sizing the DNA fragments. The sizes of some ladder bands are indicated.
