Figure 5.
Determination of 8-oxodG in 1 mL pH 5.5 buffer containing 1% fat-free milk, 1% fetal calf serum and 1% human serum spiked with 40 μg of oxidized DNA reacted with Fenton's reagent for 45 s. Control SWVs were measured in the same media without oxidized DNA. The solid bars represent the relative 8-oxodG concentration in each solution spiked with the same amount oxidized DNA. The dashed bars represents controls without spiked oxidized DNA. (Standard deviations are from three independent sensors)
