Detection of cellular redox reactions and antioxidant activity assays

Living organisms are continuously exposed to reactive oxygen species (ROS) during their lifespan. Small amounts of ROS can act as signal transduction molecules. However, excess ROS cause oxidative stress resulting in multiple adverse effects such as protein and lipid oxidation as well as DNA damage. Cells have developed an antioxidant defense system to maintain the balance between ROS production and scavenging, but imbalance often occurs leading...
