Fig. 6: Typical neutralization curves expected from the PNA.

From: Quantification of SARS-CoV-2 neutralizing antibody by wild-type plaque reduction neutralization, microneutralization and pseudotyped virus neutralization assays

Fig. 6

Poorly neutralizing sera (yellow) do not cross the dotted line corresponding to 50% of the luminance value of the pseudotyped virus control. Sera in the test range (blue and orange) all cross the 50% neutralization and yield reportable titers. Highly neutralizing sera (green) do not cross the 50% neutralization and must be retested at a higher initial dilution.
