Microscopy studies of oxidative stress have often consisted of only immunocytochemical localization or only cytochemical localization studies. However, correlative studies on the same sections provide more useful data in interpreting oxidative and nitrosative stress. Cellular sites of superoxide and hydrogen peroxide production can be identified using cerium-based cytochemical localization of NADH oxidase enzymatic activity, while areas of nitrosative stress can be identified by immunocytochemical localization of nitrotyrosine in the same sections of tissue.
