Phosphoglucose Isomerase (PGI) Assay Kit                                                                                                                                               Price

Product Description: Phosphoglucose isomerase (PGI) mediates the interconversion between glucose-6-phosphate (G6P) and
fructose-6-phosphate (F6P) in glycolysis and gluconeogenesis. Since the enzymatic step is reversible, the direction of the reaction is determined
in part by G6P and F6P concentrations. In addition to its role in glucose metabolism, PGI also functions extracellularly. PGI secreted by cancer
cells is known as autocrine motility factor (AMF), which through AMF receptor promotes cancer metastasis. PGI has also been described as a
neurotrophic factor and maturation factor in its diverse extracellular function. Clinically, PGI deficiency can lead to hemolytic anemia due to
impaired glycolysis in red blood cells, and elevated serum levels of PGI can be a prognostic biomarker for several types of cancers. The PGI
activity assay kit is based on the measurement of G6P formed from F6P, and the measurement is coupled to the reduction of the tetrazolium salt
INT in a NADPH-coupled enzymatic reaction. Since the INT reaction product exhibits an absorption maximum at 492 nm, the intensity of the red
color formed is increased in response to increased PGI activity. The PGI Assay Solution should be stored at -80ºC, and will remain stable for
many years at -80ºC..

Alphabetical Listing
Mice were fed methionine-choline deficient diet
(MCDD) for 6 weeks. Serum (left) and liver (right) PGI
enzyme activities were assayed by the PGI Assay kit.
The results show that PGI enzyme can be a blood
marker for non-alcoholic steatohepatitis (NASH).
