General description

Note: 1 KU = 1000 units.
Recombinant, Aspergillus niger glucose oxidase. Catalyzes the oxidation of β-D-glucose to D-glucono-ω-lactone and hydrogen peroxide. Also catalyzes the conversion of D-glucono-ω-lactone to gluconic acid. Each molecule of enzyme contains 2 molecules of FAD, which are essential for enzyme activity. Optimal pH = 6.5 with >95% maximal activity at pH 6.0-7.0. Useful for enzymatic assay of glucose. May also be conjugated to antibodies or antigens for use in ELISA procedures.

Other Notes

Heinz, F. and Beushausen, T.W. 1981. J. Clin. Chem. Clin. Biochem. 19, 977.
One unit is defined as the amount of enzyme that will oxidize 1.0 mmol of β-D-glucose per minute at 25°C, pH 7.0.

Preparation Note

Following reconstitution, aliquot and refrigerate (4°C). Stock solutions are stable for up to 3 months at 4°C.
