1. 靈敏的定量測定過氧化氫

2. *低檢測限為15ng/ml

3. 采用比色方法，使用簡便

過氧化氫是氧還原途徑的產(chǎn)物，由分子氧雙電子還原或者超氧陰離子自由基單電子還原產(chǎn)生。過氧化氫為強(qiáng)氧化劑，其濃度水平必須準(zhǔn)確檢測以完全確認(rèn)被研究系統(tǒng)的氧化狀態(tài)。ND的過氧化氫檢測試劑盒提供了快速，靈敏，定量的檢測化學(xué)或生物系統(tǒng)中過氧化氫水平的方法。檢測方法基于二甲酚橙和三價(jià)鐵形成的復(fù)合物顯色反應(yīng)，而三價(jià)鐵由過氧化物氧化二價(jià)鐵得到。反應(yīng)可以比色定量化，過氧化物的*低檢測限為15ng/ml。該試劑盒是Diagenes過氧化物檢測試劑盒的補(bǔ)充，通過先后使用兩個(gè)試劑盒，研究者就可以定量檢測氧還原途徑的前兩步反應(yīng)。

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.
