Detection of type III IFN in biological samples by ELISA and bioassay. (A, B) IFN-λ2/3 detection by ELISA (A) and bioassay (B) in the serum of AG129 mice 2 or 4 days after electroinjection of mouse IFN-λ3 (mIFN-λ3) expressing (pCS59) or empty (pcDNA3) plasmids, 2 days after injection of pCS59, or 3 days after infection with mouse norovirus. IFN-λ detection in the serum by ELISA was performed without UV exposure to keep maximal sensitivity. (C, D) IFN-λ2/3 detection by ELISA (C) and bioassay (D) in the bronchoalveolar lavage of BALB/C mice, 5 days postinfection with RSV, compared to control mice (mock). BALF were UV-exposed before testing. (A–D) The horizontal dotted line represents the LOD. Mann–Whitney: */**indicates a significant difference compared to pcDNA3 group at days 2 or 4 (A, B) or compared to mock (D). BALF, bronchoalveolar lavage fluid; RSV, respiratory syncytial virus.
