Immobilization support, process for producing the same, electrode, process for producing the same, electrode reaction utilizing apparatus and process for producing the same

An electrode comprising:

• an immobilization carrier including
• glutaraldehyde, poly-L-lysine,
• an electron acceptor compound wherein the electron acceptor compound has at least one amino group, and
• an 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.
