Description
Oxidoreductase that catalyzes the conversion of D-glucose to D-glucono-1,5-lactone which hydrolyzes spontanously to gluconate. Take advantage of the enhanced liquid stability. Rely on the proven diagnostic quality of this product.
Abbr
Chemically modified GOD (Aspergillus niger)
Applications
Use Glucose Oxidase (GOD), chemically modified for the determination of α-amylase and D-glucose or O2.
Appearance
Yellowish white lyophilizate
Activity
>20 U/mg lyophilizate
Contaminants
Catalase: <20 U/mg lyophilizate
Michaelis Constant
Acetate buffer, pH 5.0, +25°C: 3.6 x 10-2 mol/l Potassium phosphate buffer, 0.2 mol/l, pH 7.5, +25°C: 4.8 x 10-2 mol/l
Specificity
Glucose oxidase is specific for β-D-glucose. O2 can be replaced by hydrogen acceptors such as 2,6-dichlorophenol indophenol.

At +2 to +8°C within specification range for 12 months. Store dry.
Inhibitors
Ag+, Hg2+, Cu2+, 4-choloromercuribenzoate, D-arabinose (50%). FAD binding is inhibited by several nucleotides.
