Chemiliminescence determination of lipid hydroperoxides in biological fluids
- 33 Downloads
To evaluate the oxidative stress under clinical conditions, a procedure is developed for the chemiluminescence determination of the total concentration of lipid hydroperoxides based on their oxidation in the presence of microperoxidase and chemiluminescence activator isoluminol in a borate buffer solution (pH 10.0). The limit of detection for linoleic acid hydroperoxide is 16 nM. The procedure is used to determine lipid hydroperoxides in follicular fluid lipoproteins and in plasma of patients undergoing extracorporeal fertilization.
