Source: Escherichia Coli.Sterile Filtered colorless solution.NQO1 belongs to the NAD(P)H dehydrogenase (quinone) family and encodes a cytoplasmic 2-electron reductase. NQO1 acts as an imperative part of cellular antioxidant defense by detoxifying quinines therefore preventing the formation of reactive oxygen species. It seems that NQO1 serves as a quinone reductase relating to conjugation reactions of hydroquinons involved in detoxification pathways in addition to biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis. Altered NQO1 expression is seen in many tumors and also linked to Alzheimera€(TM)s disease. NQO1 gene mutations are linked to tardive dyskinesia which is an increased risk of hematotoxicity after exposure to benzene, and susceptibility to various forms of cancer.NQO1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 294 amino acids ( 1-274aa ) and having a molecular mass of 33.0 kDa. NQO1 is fused to a 20 amino acid His tag at N-terminus and purified by proprietary chromatographic techniques.
