Culture supernatant from CH6aORF_22m (Figure 4A) transfected Huh7.5.1-VISI-mCherry cells was passaged to naïve cells. The first- and second-passage viruses were sequenced for the ORF. Mutations identified in the viruses are listed. Two capital letter separated by a slash indicates a nucleotide quasispecies of 50/50 in sequencing reads. Dot (⋅), indicates no change for the original nucleotide. Nucleotides in shading indicate that these nucleotides were engineered into the recombinant plasmid. Sequence analysis of CH6aORF_26m revealed that no additional mutations were identified. aFour complete coding changes (I413T/Q1120K/K1648Q/A2941V) were engineered into Ch6aORF_22m to make CH6aORF_26m (Figure 4A).
