QUANTIFICATION METHOD OF ETHANOLAMINE PHOSPHATE, OXIDE REDUCTASE FOR QUANTIFICATION, COMPOSITION FOR QUANTIFICATION, KIT FOR QUANTIFICATION AND SENSOR FOR QUANTIFICATION

摘要

To provide a novel quantification method for measuring the concentration of EAP which is a biomarker of depression, an enzyme for quantification, a kit for quantification and a sensor for quantification. Provided is a quantification method of ethanolamine phosphate that comprises adding an oxide reductase to a sample containing ethanolamine phosphate. The concentration of ethanolamine phosphate may be determined by reducing a mediator by adding the oxide reductase and then reacting the thus reduced mediator with a reagent. Alternatively, the concentration of ethanolamine phosphate may be determined by adding an oxidase as the oxide reductase and then reacting the thus produced hydrogen peroxide with a reagent.
