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

29. An electrode comprising:

an immobilization carrier containing a first compound having at least two groups capable of polymerizing with a compound having at least one carboxil group, and a second compound having at least one carboxyl group; and

an electron acceptor compound wherein the electron acceptor compound has at least one amino group; and

an enzyme.

30. The electrode according to claim 29, further comprising a coenzyme.

31. The electrode according to claim 30, wherein the coenzyme has at least one amino group.
