Antiviral activity of lectins against mutant strains and epidemic variants by pseudovirus-based neutralization assay. (A) Neutralization susceptibility of mutant strains to lectins. The fold difference of IC₅₀ is present by different colors, i.e. under 4-fold change in white. Fold difference was calculated by dividing the mean IC₅₀ (mutant) by mean IC₅₀ (WT). Antiviral activity of lectins to three epidemic variants B.1.1.7 (B), B.1.351 (C) and P.1 (D) were determined. Data are from three independent experiments, and the error bars indicate the SDs from the mean values.
