Figure S1. Schematic of beta-lactamase reporter assay. Figure S2. Schematics of newly integrated sequences retrotransposed by L1. Figure S3. Standardized blue and green cell populations as controls for flow cytometry analysis. Figure S4. Dense maintenance methylation of pre-existing L1 retrotransposons in cultured human colorectal cancer (HCT116) cells is reduced dramatically in DNMT1 and DNMT3b methyltransferase double knockout cells.
