Amplite® Colorimetric Phosphofructokinase (PFK) Activity Assay Kit
The Amplite® Colorimetric Phosphofructokinase (PFK) Activity Assay Kit provides a simple and direct procedure for precise measurement of PFK enzyme activity in various biological samples. This kit is based on a coupled enzyme assay, in which fructose-6-phosphate in the presence of ATP is converted to fructose1,6-diphosphate and ADP by PFK enzyme. This ADP is then converted to AMP and NADH by an enzyme mix. The resulting NADH reduces a colorless substrate to a colored product which absorbs at 450 nm and is proportional to the PFK activity present. One unit (U) is the amount of enzyme that catalyzes the reaction of 1 µmol of substrate per minute. Phosphofructokinase (PFK) is an enzyme of glycolysis pathway catalyzing the conversion of fructose-6-phosphate to fructose-1,6-diphosphate. This is a crucial step of glycolysis as this reaction determines the overall rate of glycolysis. PFK enzyme activity is regulated by multiple cofactors and post-translational modifications. Deficiencies in PFK activity are linked to a rare genetic disorder known as glycogen storage disease type VII (GSD-VII), also known as Tarui disease. Additionally, deficiencies in PFK activity may also contribute to exercise-induced myopathy and rhabdomyolysis in certain individuals.
NADH dose response was measured using the Amplite® Colorimetric Phosphofructokinase (PFK) Assay Kit. The measurements were taken on a 96-well clear bottom microplate after a 30-minute incubation period using a ClarioStar microplate reader (BMG) at 450 nm.
