Fluorescence intensity analyzed by flow cytometry. b Histogram overlays demonstrating the detection of anti-S-RBD human IgG antibody (left) and soluble ACE2-Fc (right) as positive controls for plasma antibody assay. c Representative patient plasma titration. Healthy control plasma at 1:100 dilution was used as a negative control. Serial dilutions were used in the flow cytometry overlay. d Comparison of IgG antibody levels captured by S-RBD, S1 subunit of spike, S1 N terminal domain (NTD), S2 extracellular domain (ECD) and nucleocapsid protein coated beads ( n = 46 biologically independent samples). e Correlation and comparison of bead-based assay S-RBD IgG antibody levels with ELISA-based assay ( n = 44). Two-tailed Mann–Whitney U test was used to determine the statistical significance in ( d ) and two-tailed Spearman’s was used for correlation significance in ( e ). Horizontal bars in ( d ) and ( e ) indicate mean values.
