H2O2 production
Oxidative stress plays an important role in many pathological conditions, therefore mitochondrial (ROS) measurements are crucial for understanding a disease and for evaluating specific treatments. Evaluation of hydrogen peroxide (H2O2) emission flux by fluorescence can be used to detect H2O2 production in biological samples. Mitochondrial H2O2 emission flux is a balance between H2O2 generation, superoxide (O2•-) dismutation and the H2O2 scavenging. Mitochondrial antioxidant systems (which scavenge ROS) can be stimulated in specific physiopathological conditions masking the real ROS generation. Auranofin (AF) is an inhibitor of thioredoxin reductase (TrxR). AF can be used to quantify the relative contribution of one of the main antioxidant systems in mitochondria: Trx system. Additionally, dinitrochlorobenzene (DNCB), an inhibitor of glutathione (GSH) can be used to obtain the GSH contribution scavenging H2O2.
