8-oxodG formation in calf thymus DNA measured with HPLC/ED after 30 minutes exposure to A) SRM2975 and B) SRM1650 and C) ASPM; ■ filter 1, ▲ filter 2, △ filter 3, ○ filter 4, ◆ filter 5. For SRM2975 and SRM1650 dots represents mean ± SEM; n = 3. The DNA was incubated at 37°C with 5 mM H₂O₂. For ASPM, the DNA was incubated at 37°C with 10 μM H₂O₂.
