Triose Phosphate Isomerase Activity Assay Kit (Colorimetric) is used to measure Triose Phosphate Isomerase activity.
Triose Phosphate Isomerase (TPI or TIM: EC 18.104.22.168) is an important enzyme for glycolysis. It reversibly interconverts dihydroxyacetone phosphate and glyceraldehyde-3-phosphate, thus maintaining the equilibrium of these two triose phosphates. TPI connects glycolysis to pentose phosphate pathway and lipid metabolism. It is a stable homodimer found in almost all organisms. In humans, TPI deficiency is a rare multisystem disorder and leads to progressive neurological dysfunction, characterized by hemolytic anemia, cardiomyopathy and progressive neuromuscular impairment. Triose Phosphate Isomerase Activity Assay Kit (Colorimetric) provides a quick and easy way for monitoring Triose Phosphate Isomerase activity in a variety of samples. In this kit, Triose Phosphate Isomerase converts dihydroxyacetone phosphate into glyceradehyde-3-phosphate, which reacts with the Enzyme Mix and Developer to form a colored product with strong absorbance at 450 nm. The assay is simple, sensitive, and high-throughput and can detect Triose Phosphate Isomerase activity as low as 40 mU/mL.
