Fig. 7. Levels of anti-RBD and anti-S1 IgG antibodies measured by C19BA correlate with neutralization capacity of serum samples.

Fig. 7

a Neutralization assay performed on samples from different cohorts of individuals as indicated, including healthy and seropositive donors (n = 77). b Correlation of gMFI values obtained by C19BA and % Inhibition obtained by the neutralization assay for anti-RBD IgG (left), anti-S1 IgG (middle), and anti-N IgG (right) (n = 56). Pearson correlation coefficients (r) and their corresponding p values are shown.
