Detection of lipid hydroperoxides and hydrogen peroxide at picomole levels by an HPLC and isoluminol chemiluminescence assay.
An isoluminol assay is utilized for the detection of hydrogen peroxide and lipid hydroperoxides in biological samples. The combination of this assay as a post-column detection for HPLC avoids interference of antioxidants and enables characterization of hydroperoxides at picomole levels. Two useful HPLC conditions for the separation of hydrogen peroxide, lipid hydroperoxides, antioxidants, and unoxidized lipids are described.
