Low serum diamine oxidase (DAO) activity levels in patients with migraine [PDF]

open access: closedJournal of Physiology and Biochemistry, 2017
Histamine intolerance is a disorder in the homeostasis of histamine due to a reduced intestinal degradation of this amine, mainly caused by a deficiency in the enzyme diamine oxidase (DAO). Among the several multi-faced symptoms associated with histamine intolerance, headache is one of the most recognized and disabling consequences.

Prediction of the amount and rate of histamine degradation by diamine oxidase (DAO)

Food Chemistry, 2012
Histamine is a biogenic amine that forms in a variety of foods and can cause food poisoning at high concentrations (>500 ppm). In situations where the formation of histamine in food cannot be prevented through refrigeration, diamine oxidase (DAO) enzyme may be used to degrade histamine to safe levels.

A Spectrophotometric Method for Determination of Diamine Oxidase (DAO) Activity

Acta Physiologica Scandinavica, 1959
Abstract.If diamine oxidase is allowed to act upon the diamine putrescine, a cyclic compound, δl‐pyrroline, will be formed, which in turn reacts with o‐aminobenzaldehyde to form a yellow compound. These reactions have been taken as a starting point for a photometric method for determination of diamine oxidase.

An improved spectrophotometric assay for histamine and diamine oxidase (DAO) activity

open access: closedAgents and Actions, 1985
Diamine oxidase or its substrates can be measured using a coupled reaction with peroxidase and the chromogen 3-methyl-2-benzothiazolone hydrazone (MBTH) with an appropriate acceptor such as 3-(dimethylamino)benzoic acid (DMAB). This method provides a more rapid and sensitive method of measuring histamine than current colorimetric assays; using this ...
