Ascorbate Peroxidase (APX) Activity Assay Kit

Ascorbate peroxidase (APX) is composed of three subunits of cytoplasm, peroxisome and chloroplast isozymes. APX is unique to plants and algae, and is necessary to protect chloroplasts and other cellular components from damage by hydrogen peroxide and hydroxyl radicals. APX is the core component of ascorbic acid-glutathione cycle, which is the main hydrogen peroxide detoxification system of plant cells under abiotic stress.
