Sera from Convalescent SARS Patients Cross-Neutralize SARS-2-S-Driven Entry

Pseudotypes harboring the indicated viral surface proteins were incubated with different dilutions of sera from three convalescent SARS patients or sera from rabbits immunized with the S1 subunit of SARS-S and subsequently inoculated onto Vero cells in order to evaluate cross-neutralization potential. The average of three independent experiments performed with triplicate samples is shown. Error bars indicate SEM. Statistical significance was tested by two-way ANOVA with Dunnett posttest.
