Figure 5. Bactericidal antibiotics induce DNA and RNA oxidation.
(A, B), ELISA-based determination of 8-oxo-dG and 8-oxo-G on total DNA and RNA, respectively. E. coli were treated with 10 mM H2O2, 10 μg/mL Amp, 10 μg/mL Kan, or 250 ng/mL Nor for 60 minutes. Statistical significance is shown (*: p ≤ 0.05) using the untreated control at 60 minutes for determination.
