6-Phosphogluconate (6-PGA) is an intermediate of both Pentose Phosphate Pathway (PPP) and Entner-Doudoroff Pathway. It is produced by the hydrolysis of 6-Phosphogluconolactone, catalyzed by 6-Phosphogluconolactonase. In the Pentose Phosphate Pathway, 6-PGA is utilized by 6-Phosphogluconate Dehydrogenase to generate ribulose-5-Phosphate and NADPH. These products are important for nucleic acid synthesis and various anabolic processes. In Prokaryotes, 6-Phosphogluconate is the main metabolite of Entner-Doudoroff pathway, and is converted into Pyruvate using both 6-Phosphogluconate Dehydratase and 2-Keto-3-Deoxyphosphogluconate aldolase. Recent studies show that long-term exposure to glucose perturbs the Pentose Phosphate Pathway, causes significant accumulation of 6-Phosphogluconate and impairs beta cell function. Measurement of 6-Phosphogluconate levels therefore is important for evaluating Pentose Phosphate Pathway, developing therapeutic approaches for diabetes research, and analyzing the Entner-Doudoroff Pathway in bacteria. BioVision’s 6-Phosphogluconate assay kit can be used with a variety of sample types. In this assay, 6-Phosphogluconate is converted to Ribulose-5-Phosphate by 6-Phosphogluconate Dehydrogenase in the presence of NAD, to form NADH, which reduces a probe and generates strong absorbance at 450 nm. This 6-Phosphogluconate Assay Kit is simple, sensitive & easy to use and can detect 6-Phosphogluconate levels lower than 20 µM.

What is the exact volume of sample required for this assay?
There is no specific volume we can recommend for the amount any sample to be used since it is completely sample concentration and quality based. You have to do a pilot expt with multiple sample volumes to determine the optimal volume which gives a reading within the linear range of the standard curve. Please refer to the citations for this product to see what other clients have used with similar sample types.
Do you have trial sizes of this kit?
Unfortunately, we do not have trial sizes of this kit available. However, if you are based in the US or Canada, we will give you a 10% off list price introductory discount on its purchase price. If you are based out of this area please contact your regional BioVision distributor.
Can we purchase individual components of this kit?
Yes, you can purchase any of the kit's components without the whole kit. Please refer to the component Cat #s mentioned on the datasheet for ordering.
Can we use an alternate buffer for sample preparation (cell lysis, sample dilutions etc)?
Our assay buffers are optimized for the reactions they are designed for. They not only contain some detergents for efficient lysis of your cells/tissue, but also contain some proprietary components required for the further reactions. Therefore, we highly recommend using the buffers provided in the kit for the best results.
