Selection of Susceptible Cell Lines
A total of 26 different cell lines were infected with pseudotyped viruses with either SARS-CoV-2 S (A) or VSV G (B). The infected cell lysates were diluted by 10× and analyzed for luminescence activities (RLU). All results were obtained from three independent experiments (mean ± SEM). When the RLU for the tested cell reached 1% of that for Huh-7, it was deemed as a permissive cell line. The dash line indicates the 1% RLU value of Huh-7 cell.
