Abstract

An immobilization carrier containing an electron acceptor compound is used in addition to glutaraldehyde and poly-L-lysine to immobilize an enzyme and an electron acceptor compound simultaneously to an electrode. For example, here are used diaphorase as the enzyme and 2-amino-3-carboxy-1,4-naphthoquinone (ACNQ) as the electron acceptor compound.

Claims (4)

1. An electrode comprising:

an immobilization carrier which contains a first compound having at least two groups capable of polymerizing with amino groups or amino groups, and a second compound containing amino groups or amino groups;

an electron acceptor compound wherein the electron acceptor compound is 2-amino-3-carboxy-1,4-naphthoquinone (ACNQ), being bonded to at least one of the first compound and second compound of the immobilization carrier; and an enzyme; wherein the enzyme is diaphorase.

2. An electrode according to claim 1 , wherein the immobilization carrier has a structure in which the first compound and second compound are coupled by cross-linking.
