HEK293T ATG5 KO cells were generated by genomic knock out using CRISPR Cas9. To this end, 3rd generation lentiviral vectors were generated as described before65 using pSicoR-CRISPR-PuroR CRISPR/Cas966 (link) constructs harbouring an ATG5 targeting sgRNA or a non-targeting (NT) sgRNA. (NT: ACGGAGGCTAAGCGTCGCAA, ATG5: AACTTGTTTCACGCTATATC)67 (link) as the transfer plasmid. HEK293T cells were transduced with the lentiviral vectors and 3 days post-transduction separated into individual cells using limited dilution. The individual cells were grown into clonal cell lines and screened for ATG5 KO using Western blot analysis (anti-ATG5 antibody, Cell Signaling Technology, #2630). Clones with a conformed knock out were expanded and stocks were conserved by cryo preservation.
