Product Description
General Description:
Glucose Dehydrogenase (FAD-dependent) is an enzyme that catalyzes the oxidation of glucose to produce gluconic acid and hydrogen peroxide. This enzyme requires FAD (Flavin adenine dinucleotide) as a cofactor to function.
This lyophilized powder is a highly purified form of Glucose Dehydrogenase (FAD-dependent) that has been produced using recombinant DNA technology.

The Glucose Dehydrogenase (GDH) is highly specific for the conversion of β-D-glucose and has low efficiency towards other monosaccharides. It is a fast and thermally stable enzyme that does not produce precipitation or turbidity after completion of the reaction.
