Human Hexokinase (HK) Inhibitor Screening Kit (Colorimetric)

Hexokinases (HK, EC: 2.7.1.1) are found in many organisms including bacteria, plants and mammals and play an important role in glucose metabolism. The Hexokinase family phosphorylates glucose and generates glucose-6-phosphate for glycolysis. Four Hexokinase isoforms (HK-I, II, III and IV) are found in numerous species. HK-I, HK-II and HK-III have low affinity for glucose, one of their natural substrates, while HK-IV show high affinity for this monosaccharide. Recent studies have found increased hexokinase activity in various human metastatic tumors. Moreover, Hexokinase II (HKII) is the main isoform of the Hexokinases and is responsible for malignant phenotypes. HKII binds to the outer mitochondrial membrane via the Voltage-Dependent Anion Channel (VDAC), a Porin-like protein. HKII has become an attractive therapeutic target for its role in cancer metastasis. BioVision’s Human Hexokinase II (HKII) Inhibitor Screening kit uses the HKII’s ability to convert glucose into glucose-6-phosphate. Glucose-6-phosphate is oxidized by glucose-6-phosphate dehydrogenase to form NADH, which reduces a probe that shows strong absorbance at 450 nm. In the presence of Bromopyruvic Acid, reactions are impeded, thus decreasing the rate and/or extent of generation of Hexokinase -dependent absorbance at OD 450 nm. Hexokinase Inhibitor Control is included to compare the efficacy of test inhibitors. This kit provides a sensitive, quick, and easy method for screening potential inhibitors of Hexokinase. The assay is high-throughput adaptable and can be performed in less than 30 min

A simple and high:throughput adaptable assay kit used to colorimetrically (450 nm) screen/study/characterize potential inhibitors of human Hexokinase within 30 min.

Colorimetric assays or detection use UV absorption or enzymatic color reaction.Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.

Tissue, pathway, proteinase, peptidase, protease ,acrosin, lipoprotein, activator, caspase, trypsin, papain, esterase inhibitors are proteins or receptor ligands or receptor antagonists that bind to an enzyme receptor and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. Not all receptor antagonist that bind to enzymes are inhibitors; enzyme activator ligands or agonists bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.
