1. An electrode comprising:
- an immobilization carrier includingglutaraldehyde, poly-L-lysine,an electron acceptor compound wherein the electron acceptor compound has at least one amino group, andan enzyme, and further wherein the electron acceptor compound is combined with a cross-linking agent and the electron acceptor compound functions to support cross-linking between glutaraldehyde and poly-L-lysine, and further wherein the enzyme and electron acceptor compound are immobilized simultaneously to form an enzyme-immobilized electrode, and an aldehyde group at one end of the glutaraldehyde and an amino group of the poly-L-lysine form and amide linkage and an aldehyde group at another end of the glutaraldehyde and the amino group of the enzyme simultaneously form an amide linkage to cross-link.

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.
