Total Antioxidant Capacity (TAC) - CUPRAC Colorimetric Assay

Oxidants, such as reactive oxygen species (ROS) can generate free radicals that can cause severe oxidative damage to cellular lipids, membranes, proteins, and DNA. Antioxidants can scavenge these free radicals and prevent cellular oxidative stress. Antioxidants are widely used as dietary supplements and in the industry as preservatives in food and cosmetics. Measurements of the total antioxidant capacity (TAC) are used as an integrated index to assess their ability to counteract oxidative stress-induced damage in cells.
