Abstract
The reactive oxygen species produced endogenously are essential to life, being involved in several biological functions. However, when produced at higher levels, these reactive species become highly harmful, causing oxidative stress through the oxidation of biomolecules, leading to cellular damage. The study in the field of ROS associated biological functions and/or deleterious effects requires new sensitive and specific tools in order to enable a deeper insight on its action mechanisms. Here, we discuss several methods related to the detection of reactive oxygen species.
Keywords: Catalase, Fluorescence, Fluorescent assays, Free radicals, Hydrogen peroxide, Mitochondria, Superoxide dismutase.
