Product overview
6-Phosphogluconate Assay Kit (Colorimetric) (ab211071) provides a convenient method to detect 6-phosphogluconate (6-PGA) in cell and tissue lysates. In this assay, 6-phosphogluconate is converted to ribulose-5-phosphate by 6-phosphogluconate dehydrogenase in the presence of NAD+. NADH formed in the reaction reduces the probe present in the reaction mix, generating a strong absorbance at OD 450 nm. This absorbance is proportional to the amount of 6-PGA present in the samples.This assay kit is fast, sensitive and high-through adaptable. It can measure less than 20 µM of 6-phosphogluconate present in the sample.

Notes
6-phosphogluconate (6-phosphgluconic acid, 6-PGA) is an intermediate of both Pentose Phosphate Pathway (PPP) and Entner-Doudoroff Pathway. In the Pentose Phosphate Pathway, 6-PGA is converted by 6-phosphogluconate dehydrogenase into ribulose-5-phosphate, a precursor for the synthesis of nucleic acids. In prokaryotes, 6-PGA is the main metabolite of the Entner-Doudoroff pathway, and is converted into pyruvate by both 6-phosphogluconate dehydratase and 2-keto-3-Deoxyphosphogluconate aldolase.
Recent studies show that long-term exposure to glucose perturbs the PPP, causing significant accumulation of 6-PGA and impairment of beta cell function in the pancreas. Measurement of 6-PGA levels is important when evaluating therapies for diabetes research.
In pathological bacteria, measurement of 6-PGA levels and functionality of Entner-Doudoroff pathway can be used for clinical and diagnostic purposes.
