DPPH Free Radical Scavenging Capacity Assay Kit

DPPH free radical is a very stable nitrogen-centered free radical. It is one of the important indicators of the samples antioxidant capacity and is widely used in the research of antioxidant foods, health products and pharmaceuticals. The DPPH radical has a single electron, and its alcohol solution is purple, with strong absorption at 515 nm. When an antioxidant present, DPPH free radicals are cleared, the solution color becomes lighter, and the absorbance at 515 nm decreases.
