NADPH-cytochrome P450 reductase (CPR, EC 1.6.2.4) is a ~78 kDa membrane-bound flavoenzyme that catalyzes the transfer of electrons from NADPH to members of the cytochrome P450 monooxidase (CYP) enzyme family in the endoplasmic reticulum. As CPR is required for the function of all CYP isozymes, it plays a critical role in the metabolism of drugs, organic pollutants and other xenobiotic compounds, in addition to its role in biosynthesis of certain vitamins and steroid hormones. BioVision’s human CPR ELISA Kit is based on the standard principle of a sandwich enzyme-linked immunosorbent assay. A human CPR-specific antibody is coated on the 96-well plate. Standards or samples are then added to the appropriate wells with a biotin-conjugated antibody specific to CPR. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each well and incubated. After TMB substrate solution is added, only those wells that contain CPR, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color to form a blue product. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change from blue to yellow is measured spectrophotometrically at 450nm . The density of yellow color is proportional to the human CPR captured onto the plate. The concentration of CPR in the samples is then determined by comparing the O.D. of the samples to the standard curve. This ELISA kit shows no detectable cross-reactivity with related isoforms. Detection Range: 0.156 ng/ml – 10 ng/ml. Sensitivity: 0.156 ng/ml. Assay Precision: Intra-assay CV<10% and Inter-assay CV<12%.
