Bioactivity
(The cytochrome P450 enzyme CYP2E1 catalyzes the oxidative metabolism of many solvents and other small organic molecules. CYP2E1 is expressed in adult and fetal human liver in addition to extrahepatic tissues such as lung and placenta. Treatment of primary cultures of human hepatocytes with ethanol induces CYP2E1 protein, and this is consistent with the finding that hepatic CYP2E1 protein and mRNA levels are increased in individuals with alcoholism. Although only a few drugs (e.g., acetaminophen have been identified as substrates for CYP2E1, many low molecular weight procarcinogens are activated by this cytochrome P450 (P450). Chlorzoxazone 6-hydroxylation, N-nitrosodimethylamine N-demethylation and p-nitrophenol hydroxylation can be used to measure the catalytic activity of CYP2E1. Thus, the recombinant mouse CYP2E1 activity was measured by its ability to hydroxylate p-nitrophenol to p-nitrocatechol. The reaction was performed in 50 mM potassium phosphate, pH 7.4 (Assay Buffer), initiated by addition 20 uL of 500 ug/ml CYP2E1 to 10 uL of 5 mM substrate p-nitrophenol and 30 ul of 26 mM NADPH in a total volume of 500 ul. Incubated at 37 degree C for 30min, then read at a wavelength of 535 nm after acidification of the reaction mixture with trichloroacetic acid followed by neutralization using 2 M NaOH.)

Product Notes
The CYP2E1 cyp2e1 (Catalog #AAA161819) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Cytochrome P450 2E1 (CYP2E1) can be used in a range of immunoassay formats including, but not limited to, Activity Assay, Cell Culture. Researchers should empirically determine the suitability of the CYP2E1 cyp2e1 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. The amino acid sequence is listed below: Pro34~Met2 73. It is sometimes possible for the material contained within the vial of "Cytochrome P450 2E1 (CYP2E1), Active Protein" 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
