Abstract

Intracellular reactive oxygen species (ROS) act as an important signaling transductor in cells, regulating almost every aspect of cell biology. Measurements of ROS production thus, offer links betweenoxidative stress and cell pathophysiology. Here, we describe a simple screening assay in intact adherent cells by fluorescence microplate readers, using dihydroethidium (DHE) and MitoSOX to measure cytosolic superoxide and mitochondrial superoxide production, respectively. This assay enables a quick and reliable assessment of ROS generation in a well-controlled environment.
