Title:
QUANTIFICATION METHOD FOR 25-HYDROXYVITAMIN D, HYDROXYLASE, COMPOSITION FOR QUANTIFICATION, KIT FOR QUANTIFICATION, ELECTRODE, SENSOR CHIP, AND SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/264946
Kind Code:
A1
Abstract:
Provided are: a new quantification method for measuring 25-hydroxyvitamin D; a hydroxylase; a composition for quantification; a kit for quantification; an electrode; a sensor chip; and a sensor. According to the present invention, it is possible to provide a quantification method for 25-hydroxyvitamin D, the method comprising adding a mediator and a hydroxylase to a sample. The method may comprise quantifying an oxidized-form mediator generated by the action of the hydroxylase, or quantifying a reduced-form mediator or oxygen being consumed.
