FIG 5.

Inhibition of WT, Kappa, Delta, and B.1.618 by recombinant ACE2-Ig decoy receptor. Recombinant ACE2-Ig was diluted at the indicated concentrations. Viral entry was determined by assessing GFP expression 48 h postinfection of the WT (A) or Kappa (B), Delta (C) and B.1.618 (D) trVLP. The dilution factors leading to 50% reduction of trVLP entry were calculated as the IC₅₀ by using GraphPad Prism software. The data shown are representative of three independent experiments with similar results, and data points represent the mean ± SD in triplicate.
