From: Longitudinal observation and decline of neutralizing antibody responses in the three months following SARS-CoV-2 infection in humans

Extended Data Fig. 3: Correlations between OD values and ID50.

a, Correlation of ID50 measured against SARS-CoV-2 pseudovirus with IgG (blue), IgM (black), IgA (red) OD values (at 1:50) against S glycoprotein, RBD and N protein (Spearman correlation, r). b, Correlation of ID50 measured using wild-type virus and ID50 measured using pseudovirus neutralization assays (Spearman correlation, r). A linear regression was used to calculate the goodness of fit (r2). The dotted lines represent the lowest serum dilution used in each assay. The lowest dilution used for the pseudovirus and wild-type virus neutralization assays are 1:50 and 1:20, respectively.
