Hydrogen Peroxide is a reactive oxygen metabolic byproduct that serves as a key regulator for a number of oxidative stress-related states. Functioning through NF-κB and other factors, hydroperoxide-mediated pathways have been linked to asthma, inflammatory arthritis, atherosclerosis, diabetic vasculopathy, osteoporosis, neuro-degenerative diseases, Down's syndrome and immune system diseases. BioVision's Hydrogen Peroxide Assay Kit is a highly sensitive, simple, direct and HTS-ready colorimetric and fluorometric assay for measuring H?O? in biological samples. In the presence of Horse Radish Peroxidase (HRP), the OxiRed Probe reacts with H?O? to produce product with color (λmax = 570 nm) and red-fluorescent (Ex/Em=535/587 nm). Th
