Figure 2. Autoradiograph of Southern hybridization of digested DlEPV genomic DNA with a 4.5 kb specific probe generated from the DlEPV R1-1 insert. Lanes 1–2: empty; Lane 3: 1 μl of the DlEPV R1-1 undigested 4.5 kb insert (positive control); Lane 4: 2 μl salmon sperm DNA (negative control); Lane 5: 5 μl EcoRI digested DlEPV genomic DNA; Lane 6: 5 μl HindIII digested DlEPV genomic DNA; Lane 7: 5 μl BamHI digested DlEPV genomic DNA.
