Results of the ELISAs plotted against the titers from the neutralization assay (n = 63). Values above the maximum or below the minimum in a test were plotted at this maximum or minimum value, respectively (Mikrogen IgA, >150.12 U/ml; Mikrogen IgG, >133.93 U/ml; Euroimmun IgA, >8.54; Serion IgA, <5.0 U/ml; Serion IgG, <3.0 U/ml and >250.0 U/ml). Mikrogen, Mikrogen recomWell SARS-CoV-2 IgA/IgG (Mikrogen, Neuried, Germany), based on the nucleocapsid; Euroimmun, Euroimmun SARS-COV-2 IgA/IgG (Euroimmun, Lübeck, Germany), based on S1 antigen; Serion, Serion ELISA agile SARS-CoV-2 IgA/IgG (Institut Virion/Serion, Wuerzburg, Germany), based on the S1/S2 ectodomain and the nucleocapsid (IgA) or S1/S2 ectodomain antigen (IgG); PRNT50, 50% plaque-reduction neutralization test. Method described in Materials and Methods. PRNT50 values of <20 were considered negative.
