Glucose 6 Phosphate Dehydrogenase Assay Kit - Information

Assay Genie's non-radioactive, colorimetric G6PDH assay is based on the reduction of the tetrazolium salt MTT in a NADPH-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.


For quantitative colorimetric determination of Glucose-6-Phosphate concentration and evaluation of drug effects on its metabolism.

Glucose 6 Phosphate Dehydrogenase Assay Kit -Key Features

  • Fast and sensitive. Linear detection range (20 sample): 0.2 to 100 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.

More Details

GLUCOSE-6-PHOSPHATE DEHYDROGENASE (G6PDH) is a cytosolic enzyme in the pentose phosphate pathway which supplies reducing energy to cells by maintaining the level of the co-enzyme nicotinamide adenine dinucleotide phosphate (NADPH). G6PDH reduces nicotinamide adenine dinucleotide phosphate (NADP) to NADPH while oxidizing glucose-6-phosphate (G6P). Humans with a genetic deficiency of G6PDH are predisposed to non-immune hemolytic anemia.

Entrez Gene Summary for G6PD Gene

This gene encodes glucose-6-phosphate dehydrogenase. This protein is a cytosolic enzyme encoded by a housekeeping X-linked gene whose main function is to produce NADPH, a key electron donor in the defense against oxidizing agents and in reductive biosynthetic reactions. G6PD is remarkable for its genetic diversity. Many variants of G6PD, mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms. G6PD deficiency may cause neonatal jaundice, acute hemolysis, or severe chronic non-spherocytic hemolytic anemia. Two transcript variants encoding different isoforms have been found for this gene.

UniProtKB/Swiss-Prot for G6PD Gene

G6PD_HUMAN,P11413Catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a route for the dissimilation of carbohydrates besides glycolysis. The main function of this enzyme is to provide reducing power (NADPH) and pentose phosphates for fatty acid and nucleic acid synthesis.

Interacts with SIRT2; the interaction is enhanced by H(2)O(2) treatment.Miscellaneous:Binds two molecules of NADP. The first one is a cosubstrate (bound to the N-terminal domain), the second is bound to the C-terminal domain and functions as a structural element.SequenceCaution:Sequence=AAA63175.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};

Post-translational modifications for G6PD Gene

  • Acetylated by ELP3 at Lys-403; acetylation inhibits its homodimerization and enzyme activity. Deacetylated by SIRT2 at Lys-403; deacetylation stimulates its enzyme activity.
  • Ubiquitination at Lys 97, Lys 171, and Lys 403
  • Modification sites at PhosphoSitePlus
