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.
