|Product Overview :
||Recombinant Human CYP2C9 allele expressed ininsect cellsis the most common in human populations studied to date and contains Arg, Ile and Gly at positions 144, 359 and 475 respectively.
||CYP2C9 is an important cytochrome P450 enzyme with a major role in the oxidation of both xenobiotic and endogenous compounds. CYP2C9 makes up about 18% of the cytochrome P450 protein in liver microsomes. Some 100 therapeutic drugs are metabolized by CYP2C9, including drugs with a narrow therapeutic index such as warfarin and phenytoin and other routinely prescribed drugs such as acenocoumarol, tolbutamide, losartan, glipizide, and some nonsteroidal anti-inflammatory drugs.
|Protein Concentration :
||5.5 mg/mL as determined using the BCA assay. Buffer: 100 mM potassium phosphate (pH 7.5), 20% (v/v) glycerol, 0.1 mM EDTA, 1 mM DTT.
|Specific Content :
||200 pmol spectral P450 per milligram of protein Cytochrome.
|Reductase Activity :
||1.19 μmol of cytochrome c reduced per minute per milligram of protein.
|Hydroxylase Activity :
||6.6+0.881 nmol/min/mg of protein. Diclofenac hydroxylation reactions were performed for 10 minutes at 37°C. Reactions were carried out in the presence of 0.1 M Tris HCl (pH 7.5), 100 μM diclofenac, 2 mM NADPH, and at a final protein concentration of 100 μg/mL. The reactions were stopped by addition of 20 μL acetonitrile/glacial acetic acid (96:4).
||−80℃; Avoid multiple freeze-thaws.
