Figure 2From: Development of an in situ assay for simultaneous detection of the genomic and replicative form of PCV2 using padlock probes and rolling circle amplificationPCV2 Infection in PK-15A cells. Path of infection in PCV2 infected PK-15A cells after a) 24 hours, b) 30 hours, c) 48 hours, d) 72 hours, e) 72 hours unligated padlock probe and f) uninfected for 24 hours. Rolling circle products from the genomic strand are seen as green dots, signals from the replicative strand as red dots, and nuclei are counterstained with DAPI (blue).Back to article page
