Abstract
Several lines of evidence suggest that reactive oxygen species are implicated in human disease, including atherosclerosis, hypertension, and restenosis after angioplasty. The measurement of F2-isoprostanes (F2-iPs), formed nonenzymatically through free radical catalyzed attack on esterified arachidonate, provides a reliable tool for identifying populations with enhanced rates of lipid peroxidation. Among F2-isoPs, 8-iso-PGF2α (also referred to IPF2α-III) and IPF2α-VI are the most frequently measured in biological fluids. A variety of methods have been proposed to measure F2-isoprostanes in urine and plasma. Mass spectrometry has been developed for the measurement of both F2-isoprostanes but its use is limited as it is time-consuming and highly expensive. We have developed validated enzyme immunoassay (EIA) and radioimmunoassay (RIA) techniques using highly specific antisera for the measurement of 8-iso-PGF2α. In contrast, the commercially available immunoassay kits are limited for their poor specificity. The measurement of specific isoprostanes, such as 8-iso-PGF2α, in urine is a reliable, noninvasive index of lipid peroxidation that is of valuable help in dose-finding studies of natural and synthetic antioxidant agents.
