Fig. 4From: Genetic diversity and different cross-neutralization capability of porcine circovirus type 2 isolates recently circulating in South KoreaViral neutralization assay using anti-PCV2 pig sera. a Anti-sera collected from SPF pigs vaccinated with Ingelvac CircoFLEX were neutralized with homologous and heterologous genotypes of PCV2. *Significantly different from control at p < 0.05. b The %VN of Fig. 4a was converted from the number of PCV2-positive cells counted per 1 × 104 cells using ArrayScan VTI HCS. Nuclei were counterstained with Heches33258. The merged images were magnified as 100 ×Back to article page
