Excess ROS must be promptly eliminated from the cell by a variety of antioxidant defense mechanisms. Cellular antioxidant enzymes and other redox molecules serve to counterbalance ROS generated in the cell.

We offer assays to measure the activity of specific antioxidant enzymes (catalase, superoxide dismutase). Additionally, you may measure the antioxidant capacity of certain biomolecules (ORAC, HORAC).
