Assessment of the neutralizing capabilities of the NAbs against SARS-CoV-2 and its mutated S D614G . Neutralizing potency measured by the neutralization assay against authentic SARS-CoV-2 (a), SARS-CoV-2 pseudovirus (b) and its mutated type S D614G (c). Data for each NAb were obtained from a representative neutralization experiment, with three replicates. Data are presented as mean ± SEM.
