DetectX®Hydrogen Peroxide比色检测试剂盒提供过氧化氢标准品以生成标准曲线。将样品与无色比色底物混合，并加入辣根过氧化物酶引发反应。将反应在室温下孵育15分钟。HRP在过氧化氢的存在下与底物反应，将无色底物转化为粉红色产物。在560 nm处读取粉红色产物。H2O2水平的增加会导致粉红色产物的产量呈线性增加。

In biological systems, incomplete reduction of O2  during respiration produces superoxide anion (O2 -·), which is spontaneously or enzymatically dismutated by superoxide dismutase to H2O2 . Many cells produce low levels of O2 -· and H2O2 in response to a variety of extracellular stimuli, such as cytokines (TGF-β1, TNF-α, and various interleukins), peptide growth factors (PDGF, EGF, VEGF, bFGF, and insulin), the agonists of heterotrimeric G protein–coupled receptors (GPCR) such as angiotensin II, thrombin, lysophosphatidic acid, sphingosine 1-phosphate, histamine, and bradykinin, and by shear stress. The addition of exogenous H2O2 , or the intracellular production in response to receptor stimulation, affects the function of various proteins including protein kinases, protein phosphatases, transcription factors, phospholipases, ion channels, and G proteins. In 1894, Fenton described the oxidation of tartaric acid by Fe2+ and H2O2. H2O2  and O2  may participate in the production of singlet oxygen and peroxynitrite and the generation of these species may be concurrent with reactions involving iron, which under some circumstances might be important contributors to H2O2 toxicity.
