Background: 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. In humans, TPI deficiency is a rare multisystem disorder and leads to progressive neurological dysfunction, characterized by hemolytic anemia, cardiomyopathy and progressive neuromuscular impairment. MyBioSource's Triose Phosphate Isomerase Activity Assay kit 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 & Developer to form a colored product with strong absorbance at 450 nm. The assay is simple, sensitive, & high-throughput and can detect Triose Phosphate Isomerase activity as low as 40 mU/ml.
Summary: Detection method- Absorbance (OD 450 nm)
Applications: - Measurement of TPI activity in various tissues and cells - Analysis of glycolysis & pentose phosphate pathway and lipid metabolism
NCBI and Uniprot Product Information
Uniprot Description
TPI1: Defects in TPI1 are the cause of triosephosphate isomerase deficiency (TPI deficiency). TPI deficiency is an autosomal recessive disorder. It is the most severe clinical disorder of glycolysis. It is associated with neonatal jaundice, chronic hemolytic anemia, progressive neuromuscular dysfunction, cardiomyopathy and increased susceptibility to infection. Belongs to the triosephosphate isomerase family. 2 isoforms of the human protein are produced by alternative promoter.

Product Notes
The Tpi1 tpi1 (Catalog #AAA841798) is an Assay Kit and is intended for research purposes only. The product is available for immediate purchase. Measurement of TPI activity in various tissues and cells Analysis of glycolysis & pentose phosphate pathway and lipid metabolism. Researchers should empirically determine the suitability of the Tpi1 tpi1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Triose Phosphate Isomerase (TPI), Assay Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
