Peroxide Assay Kit

Peroxide Assay Kit has been used to measure hydrogen peroxide level in rat tissue homogenates.

Suitable for the quantitative determination of peroxide concentration without any pretreatment in a variety of biological samples, such as serum, citrate-plasma, urine, cell lysates, and culture medium.

The Peroxide Assay Kit provides a simple and high-throughput adaptable assay for quantitative determination of peroxide concentration without any pretreatment in a variety of biological samples, such as serum, citrate-plasma, urine, cell lysates, and culture medium. This assay utilizes the chromogenic Fe³⁺ −xylenol orange reaction, in which a purple complex is formed when Fe²⁺ is oxidized to Fe³⁺ by peroxides present in the sample, generating a colorimetric (585 nm) result, proportional to the level of peroxide present. The optimized formulation reduces interference by substances in the raw samples. A concentration of 1 μM H₂O₂ equals 34 ng/mL or 34 ppb. The kit has a detection range of 0.2–30 μM (7–1,020 ng/mL) H₂O₂ in a 96 well format.

Compatible with high-throughput handling systems.

Peroxide (e.g. hydrogen peroxide H2O2), a reactive oxygen species produced through the metabolism of molecular oxygen, serves as both an intracellular signaling messenger and a source of oxidative stress. Hydrogen peroxide is generated in cells via multiple mechanisms such as the NOX-mediated ROS production by neutrophils and macrophages (respiratory burst) or by the dismutase of superoxide anions produced as a result of electron leak during mitochondrial respiration. Abnormal hydrogen peroxide production contributes to oxidative cell damage and the progression of diseases such as asthma, atherosclerosis, osteoporosis, and neurodegeneration.
