Features and Benefits

Compatible with high-throughput handling systems.

General description

Triose Phosphate Isomerase (TPI or TIM: EC 5.3.1.1) 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.

Principle

This Triose Phosphate Isomerase Activity Assay kit provides a quick and easy way for determining triose phosphate isomerase activity in a variety of samples. In this kit, triose phosphate isomerase converts dihydroxyacetone phosphate into glyceraldehyde 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.

Suitability

Suitable for detection of Triose Phosphate Isomerase in animal tissues (muscle, liver, heart, kidney, etc.), cell culture (adherent or suspension cells) and human serum or plasma.
