Figure 4From: A quantitative infection assay for human type I, II, and III interferon antiviral activitiesValidation of the assay’s ability to measure multiple interferon types. The final DsRed2 form of the assay was used to measure antiviral activity of human type I (IFNα1, IFNβ), type II (IFNγ), and type III (IFNλ1, IFNλ2, IFNλ3) recombinant bioactive interferon standards. IC50 values in pg/ml of added interferon were calculated as described, and are also shown in pmol/ml for molar comparisons.Back to article page
