Peroxidase Activity Assay Kit - Information

Assay Genie's peroxidase activity assay uses H2O2 and an electron donor dye that forms a pink color during the peroxidase reaction. The optical density (570nm) or fluorescence intensity (Ex/Em = 530/590nm) is a direct measure of the enzyme activity.


For quantitative determination of peroxidase activity.

Peroxidase Activity Assay Kit - Key Features

  • Fast and sensitive. Use as little as 10 samples. Linear detection range: colorimetric assays 2 to 50 U/L, fluorimetric assays 0.1 to 5 U/L peroxidase.
  • Convenient and high-throughput. Homogeneous "mix-incubate-measure" type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day.

More Details

PEROXIDASES (EC number 1.11.1.x) catalyze the following oxidation-reduction reactions:ROOR' + electron donor (2 e-) + 2H+ ROH + R'OH.For many peroxidases the optimal substrate is hydrogen peroxide (H2O2), but others are more active with organic hydroperoxides such as lipid peroxides. In the cell, peroxidases destroy toxic hydroxide radicals that are formed as byproducts during aerobic respiration. The peroxidases represent a large family of enzymes that are found in animals (e.g. myeloperoxidase-like enzymes), plant, fungi and bacteria (cytochrome-c peroxidase like enzymes such a horseradish peroxidase). Simple, direct and automation-ready procedures for determining peroxidase activity find wide applications.
