ABSTRACT:
Improvements in a coenzyme electrode used to electrochemically measure the activity of enzyme or substrate concentration of the enzyme easily. The coenzyme is immobilized, without using a semipermeable membrane, on the electron collector directly with the chemical bond, particularly the covalent bond, whereby the activity of the oxide-reductase requiring the coenzyme can be measured. In addition, the oxide-reductase requiring the coenzyme is also immobilized together with such immobilized coenzyme to improve the characteristics of the conventional enzyme-coenzyme immobilized electrode.
