The single isotopic enzymatic histamine assay system has been adopted for the studying of the release of histamine from sensitized human leukocytes when challenged with the appropriate allergen. It is a simple, rapid, sensitive, and reproducible method based on the use of the enzyme histamine N-methyltransferase and the high specific activity of tritiated S adenosylmethionine.
