The Protein Mask prevents Cu2\u003cbr\u003e\nreduction by proteins, enabling the analysis of only the small molecule antioxidants. The reduced Cu\u003cbr\u003e\nion is chelated with a colorimetric probe giving a broad absorbance peak around 570 nm, proportional to the total antioxidant capacity.\u003cbr\u003e\nTotal antioxidant capacity assay protocol summary:\u003cbr\u003e\n- add protein mask to samples if only measuring small molecule total antioxidant capacity\u003cbr\u003e\n- add samples and standards to wells\u003cbr\u003e\n- add Cu2\u003cbr\u003e\nsolution and incubate for 90 min at room temp\u003cbr\u003e\n- analyze with microplate reader\u003cbr\u003e\nAntioxidants play an important role in preventing the formation of, and scavenging of, free radicals and other oxidizing species. There are three categories of antioxidant species: enzyme systems (GSH reductase, catalase, peroxidase, etc.), small molecules (ascorbate, uric acid, GSH, vitamin E, etc.) and proteins (albumin, transferrin, etc.). Trolox is used to standardize antioxidants, with all other antioxidants being measured in Trolox equivalents. Measurement of the combined non-enzymatic antioxidant capacity of biological fluids and other samples provides an indication of the overall capability to counteract reactive oxygen species (ROS), resist oxidative damage and combat oxidative stress-related diseases.\u003cbr\u003e\nRelated antioxidant capacity assays and oxidative stress products\u003cbr\u003e\nThe most popular antioxidant capacity assay is Total Antioxidant Capacity Assay Kit ab65329, based on copper reduction.
