Unit Definition: One unit of Glucose Dehydrogenase (FAD-dependent) activity is defined as the amount of enzyme that will convert 1 µmole of glucose to gluconic acid and hydrogen peroxide per minute at pH 6.5 at 37°C.
Purity and Quality
≥95%(SDS-PAGE) Quality Control: The Glucose Dehydrogenase (FAD-dependent) Lyophilized Powder is tested for its activity, purity, and absence of contaminating nucleases, proteases, and endotoxins. The activity of the enzyme is measured using a spectrophotometric assay based on the production of hydrogen peroxide. The purity of the enzyme is assessed by SDS-PAGE and western blotting using specific antibodies. The absence of contaminating nucleases, proteases, and endotoxins is confirmed by gel electrophoresis and Limulus amoebocyte lysate (LAL) assay.
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.  

Glucose dehydrogenase (GDH) has a wide range of applications in various fields including biotechnology, biochemistry, and medicine. Some of the key applications are:

1.      Biosensors: GDH is widely used in the development of glucose biosensors for monitoring blood glucose levels in diabetes patients.
2.      Biofuels: GDH can be used to produce biofuels such as ethanol and butanol from renewable resources like sugar, corn, and cellulosic materials.
3.      Food and Beverage Industry: GDH is used as a biocatalyst in the production of high-fructose corn syrup, which is widely used as a sweetener in the food and beverage industry.
4.      Pharmaceuticals: GDH can be used in the synthesis of certain pharmaceuticals, such as ascorbic acid and D-gluconic acid.
5.      Bioremediation: GDH has been found to play a role in the bioremediation of environmental pollutants such as heavy metals and organic pollutants.
6.      Biotechnology: GDH has potential applications in the biotechnology industry for the production of chiral chemicals and fine chemicals.
