Figure 5From: First construction of infectious clone for newly emerging mutation porcine circovirus type 2 (PCV2) followed by comparison with PCV2a and PCV2b genotypes in biological characteristics in vitroDifferentiation of the rescued viruses with tractable marker from their parental wild-type viruses. Sal I digestion of PCR products of rescued viruses with tractable marker generated two fragments of 865 and 192 bp; Sal I digestion of PCR products of parental wild-type viruses generated only one fragment of 1057 bp. The names of the rescued viruses and parental wild-type viruses are indicated at the corresponding lane above the figure.Back to article page
