A reliable and sensitive enzyme immunoassay method for measuring 8-isoprostaglandin F2 alpha: a marker for lipid peroxidation after experimental brain injury.

摘要

The objectives of this study were to determine (1) if levels of 8-isoprostaglandin F2 alpha (8-isoPGF2 alpha), a non-enzymatically produced prostaglandin, were increased after cortical contusion and (2) if enzyme immunoassay (EIA) could be used to quantify 8-isoPGF2 alpha levels. 24 h after the contusion there was a significant rise in 8-isoPGF2 alpha compared to control levels. The levels returned to baseline by 72 h postinjury. The results show that this EIA method is a reliable and sensitive technique for measuring brain lipid peroxidation.
