Abstract:
Provided are: a method for stabilizing an ascorbic acid oxidase; a method for preserving an ascorbic acid oxidase; and a stabilized composition of an ascorbic acid oxidase. A method for stabilizing an ascorbic acid oxidase and a method for preserving an ascorbic acid oxidase, each of the methods comprising allowing an ascorbic acid oxidase to coexist with nitrous acid or a salt thereof, or a nitrous acid ester in an aqueous medium; and a stabilized composition of an ascorbic acid oxidase, which comprises an ascorbic acid oxidase being allowed to coexist with nitrous acid or a salt thereof, or a nitrous acid ester in an aqueous medium. The method for stabilizing an ascorbic acid oxidase, the method for preserving an ascorbic acid oxidase, and the stabilized composition of an ascorbic acid oxidase according to the present invention are useful for clinical diagnosis and the like.
