Product Information

• Product name

  CheKine™ Diamine Oxidase (DAO) Activity Colorimetric Assay Kit

• Application notes

  DAO catalyzed resin amine to produce aldehyde and hydrogen peroxide, and add excessive horseradish peroxidase exogenous to catalyze hydrogen peroxide to oxidize o-anisamine to produce colored substances which has a characteristic absorption peak at 460 nm. DAO activity is calculated by measuring the absorbance increase rate of this wavelength. It can test samples of tissue, cells, bacteria, plants and serum (plasma).

Additional Information

• Background

  DAO(EC1.4.3.6) is widely present in animals (intestinal mucosa, lung, liver, kidney), plants, microorganisms. It catalyzes polyamine and oxidized to aldehydes, Its activity is closely related to nucleic acid and protein synthesis and can reflect the integrity of the intestinal mechanical barrier and the degree of damage.
