                                Introduction
                                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 Alzheimer’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.
                                Description
                                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.

                                Sterile Filtered colorless solution.
                                Formulation
                                The NQO1 solution (1 mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 1mM DTT and 10% glycerol.
 
                                Stability
                                Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. 
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
                                Purity
                                Greater than 95.0% as determined by SDS-PAGE.
                                Biological Activity
                                Specific activity is > 1,000 pmol/min/ug. One unit will convert 1 pmoles resazurin to resorufin per minute at pH 7.5 at 25°C.
