Assay kits - Oxidative stress
Oxidative stress is a state when the normal reduced environment of a cell changes due to the accumulation of reactive oxygen species (ROS). These ROS like peroxides, superoxides and free radicals can cause pathological changes in the cell due to DNA damage, oxidation of amino acids, proteins, polyunsaturated fatty acids and enzyme cofacors which subsequently causes cell death due to apoptosis or necrosis.
The antioxidant enzymes within cells like catalase, superoxide dismutase (SOD), lactoperoxidases and glutathione peroxidase inhibit the production of such free radicals and thus protect cells in order to maintain the balance.
