In vitro inhibition of SARS-CoV-2 infection of Vero 76 cells by CoVS-HR1 proteins. Vero 76 cells were infected by primary viruses (B1 D614G genotype) in the presence of CoVS-HR1 proteins at varying concentrations. The percentage of inhibition was calculated according to the reduction in percentage of infected cells treated with inhibitor compared to the percentage of infected untreated control cells. The percentage of infected cells in each well was recorded by measuring the number of infected cells (labeled by antinucleocapside antibody) and the total number of cells (by Sytox Green staining) using an imaging cytometer. The data and error bars correspond to the mean and standard deviation from two independent experiments.
