Specificity and cross-reactivity of plasma Ab response. IgG Abs against SARS-CoV-2 S, S1, S2, RBD and N proteins in plasma samples from three infected individuals, Pt1, Pt2 and Pt3 (A, B and C), were detected using ELISA. Cross-reactive Abs in plasma samples against SARS-CoV S and RBD were also tested. Each plasma sample was initially diluted 1:100, followed by 3-fold serial dilution and tested in duplicate. AUC was calculated from the background-subtracted OD value using GraphPad Prism 7. AUC, area under curve;#, PBMCs at these time points were used for memory B-cell analysis.
