Immobilized alcohol oxidase, method for its preparation and measuring apparatus.

摘要

The invention relates to alcohol oxidase immobilized in the form of a thin layer on a carrier which may be prepared by at least the steps of (A) aminosilane coupling treatment of a carrier, (B) bonding a multifunctional aldehyde on the coupled amino groups, and (C) bonding an alcohol oxidase thereon. The invention further provides an alcohol measuring unit and alcohol and glucose measuring apparatus using this immobilized alcohol oxidase. According to the invention, immobilized alcohol oxidase having improved heat resistance and long life time can be obtained, and using this immobilized alcohol oxidase, excellent alcohol measuring apparatus and alcohol and glucose measuring apparatus can be easily composed.
