IF-slides to detect anti-nCoV antibodies by Immunofluorescence assay. The slides were prepared by infecting Vero cells with the first Swedish SARS-CoV-2 isolate (SARS-CoV-2/01/human/2020/SWE). The virus is fully sequenced (Genebank accession: MT093571). The slides are fixated in acetone, air-dried and preserved at -80°C. IF-analysis tested positive with SARS-CoV-2 infected human sera.
