Figure 4. In vitro pseudovirus neutralization activity of human plasma samples (1-13) against SARS-CoV-2 Spike variants; Wuhan(A ), Alpha (B ), Beta (C ). Neutralization curves of human convalescent plasma samples against pseudotyped SARS-CoV-2 variants; (A) VSV-ΔG-Sdel21 Wuhantype, (B) VSV-ΔG-Sdel21 Alpha variant carrying ΔH69-V70, N501Y, D614G, ΔY144 and (C) VSV-ΔG-Sdel21 Beta variant carrying E484K, N501Y, D614G, K417N mutations were measured as GFP signal in Vero E6 cells, and the percentage of neutralization was calculated. Data are represented as means of ±S.D. of at least two independent experiments.
