PEDV N expression in Vero E6 cells promotes growth of PEDV-AVCT12 variants.

Vero E6 and Vero E6-N cells were infected (MOI = 0.0001) with PEDV-AVCT12-mCherry carrying wild-type (A and C) or L381P (B and D) nucleocapsid variants. Infected cells were imaged at indicated time (A and B), while the supernatants were analyzed for viral production by the TCID50 assay (C and D). Figures are representative of three independent experiments. Values are averages±SEM of three independent experiments. * p p < 0.01. Scale bar, 100 μm.
