Table 2 Cytopathic effect inhibition assay with IFNβ and SGLuc-IFNβ samples

From: Method for quantification of porcine type I interferon activity using luminescence, by direct and indirect means

Sample No. samples with vesicular stomatitis virus plaques in diluted growth media
1:100 1:200 1:400 1:800 1:1600 1:3200 1:6400 1:12,800
IFNβ 0/4 0/4 0/4 0/4 0/4 2/4 4/4 4/4
SGLuc-IFNβ 0/4 4/4 4/4 4/4 4/4 4/4 4/4 4/4
  1. For determination of anti-viral activity for IFNβ and SGLuc-IFNβ samples, four wells for each dilution were evaluated for the presence of VSV plaques at 24 h post-infection. Wells were scored positive when plaques were observed
