QuantiChrom™ Glucose dehydrogenase Assay Kit | DGDH-100 | Bioassay Systems

For quantitative determination of D-glucose dehydrogenase enzyme activity and drug effects on its metabolism.


• Fast and sensitive. Linear detection range (20 μL sample): 0.5 to 200 U/L for 15 min reaction.

• Convenient and high-throughput. Homogeneous "mix-incubate-measure" type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day.

GLUCOSE DEHYDROGENASE (GDH) belongs to the family of oxioreductases, specifically those acting on the CH-OH group of donor with other acceptors. GDH participates in the pentose phosphate pathway. BioAssay Systems’ non-radioactive, colorimetric GDH assay is based on the reduction of the tetrazolium salt MTT in a NADH-coupled enzymatic reaction to a reduced form of MTT which exhibits an absorption maximum at 565 nm. The increase in absorbance at 565 nm is proportional to the enzyme activity.
