Experimental design for genome-scale CRISPR screens performed in this study. Details of these screens are provided in the methods. A Vero E6 cells transduced with the newly generated Vervet sgRNA library were infected with SARS-CoV-2 or OC43 at MOI 0.01; resistant cells were expanded and reinfected at MOI 0.1. B Two screens were performed in HEK293T-hACE2 cells transduced with the Brunello sgRNA library. In the first screen, cells were infected with SARS-CoV-2 or OC43 at MOI 0.01 and resistant cells were reinfected with either MOI 0.01 or MOI 0.1 of the corresponding virus. In the second screen, cells were infected with SARS-CoV-2 at MOI 0.3 and reinfected at MOI 0.03. In all cases, genomic DNA was extracted from multiple replicates of control cells, the initial infections, and reinfections for the purpose of sgRNA sequencing
