• Easy-to-use, Colorimetric System

Catalog Number:SG CL-204

1. 灵敏的定量测定过氧化氢

2. *低检测限为15ng/ml

3. 采用比色方法，使用简便

过氧化氢是氧还原途径的产物，由分子氧双电子还原或者超氧阴离子自由基单电子还原产生。过氧化氢为强氧化剂，其浓度水平必须准确检测以完全确认被研究系统的氧化状态。ND的过氧化氢检测试剂盒提供了快速，灵敏，定量的检测化学或生物系统中过氧化氢水平的方法。检测方法基于二甲酚橙和三价铁形成的复合物显色反应，而三价铁由过氧化物氧化二价铁得到。反应可以比色定量化，过氧化物的*低检测限为15ng/ml。该试剂盒是Diagenes过氧化物检测试剂盒的补充，通过先后使用两个试剂盒，研究者就可以定量检测氧还原途径的前两步反应。

Hydrogen peroxide is a part of the oxygen reduction pathway, produced by the two-electron reduction of molecular oxygen, or by the one electron reduction of superoxide anion radical. Hydrogen peroxide is a potent oxidant, and the levels of hydrogen peroxide must be accurately determined in order to fully characterize the oxidative state of the system under study.

National Diagnostics Hydrogen Peroxide Assay Kit is a rapid, sensitive and quantitative method for the determination of Hydrogen Peroxide in chemical or biological systems. The assay is based upon formation of a complex between Xylenol Orange and ferric iron, which is produced by the peroxide dependent oxidation of ferrous iron. This reaction is quantified colorimetrically, detecting as little as 15ng/ml of peroxide.

National Diagnostics Hydrogen Peroxide Assay is the ideal complement to our well established Diogenes Superoxide detection system. Using these kits in tandem, researchers can now quantitatively determine the first two steps in the oxygen reduction pathway.
