  • Product overview

    Abcam's Glucose 6 Phosphate Dehydrogenase Assay Kit (Colorimetric) (ab102529) is a simple, sensitive and rapid assay detects the activity of Glucose 6 Phosphate Dehydrogenase (G6PDH) in a variety of samples. In the assay, glucose 6 phosphate is oxidized, which leads to the conversion of a nearly colorless probe to an intensely colored product with an absorbance at 450nm.

    The G6PDH Assay Kit can detect as low as 0.04mU G6PDH per well.

  • PlatformMicroplate


  • RelevanceGlucose 6 phosphate dehydrogenase (G6PDH) is a cytosolic enzyme in the pentose phosphate pathway, a metabolic pathway that supplies reducing energy to cells (such as erythrocytes) by maintaining the level of the co-enzyme nicotinamide adenine dinucleotide phosphate (NADPH). The NADPH in turn maintains the level of glutathione in these cells that helps protect the red blood cells against oxidative damage. Of greater quantitative importance is the production of NADPH for tissues actively engaged in biosynthesis of fatty acids and/or isoprenoids, such as the liver, mammary glands, adipose tissue, and the adrenal glands.

Methanol lysis holds advantages over both NP-40 and mechanical lysis in that it much quicker, requiring only 2 minutes incubation at room temperature, followed by centrifugation and aspiration of the supernatant. Please find attached data from my experiment which shows that, despite identical NADH standard curves, lysis of human PBMCs in methanol leads to loss of measurable G6PDH activity when compared to NP-40 lysis.

This buffer should be fine.

We have not tested this specific combination of components in the concentrations mentioned. So there can always be some unforeseen interference, but theoretically the composition should work with this kit.

Thank you for your enquiry.
