Tests
Damage tolerance assay
To measure the DNA damage tolerance conferred by each part, we used UV irradiation as a source of DNA damage and then assayed the survival rates. Transformed
E. coli cells were plated on agar plates at different dilutions, air dried, and then exposed to different doses of UV radiation. Plates were wrapped with aluminum foil and incubated in the dark. Colony-forming units were scored after 16h incubation at 37°C. For detailed protocols, refer to the
Protocols page.
