Representative results of PCR electrophoresis with the DNA of beagle peripheral blood mononuclear cells (PBMCs). No PERV DNA or Sus scrofa cytochrome B (SsCytB) sequence was found in the canine PBMCs. DNA from porcine hepatocytes and PERV-infected canine peripheral blood mononuclear cell (PBMCs) were used as positive controls, and pure water was used as the negative control. Ladder ranged from 100 to 600 bp.
