        Test principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse NFκB-p65. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse NFκB-p65. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mouse NFκB-p65, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Mouse NFκB-p65 in the samples is then determined by comparing the OD of the samples to the standard curve.

        精密度

        Intra-assay Precision (Precision within an assay):CV%<8%

        Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

        Inter-assay Precision (Precision between assays):CV%<10%

        Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.

        回收率

        Matrices listed below were spiked with certain level of recombinant NFκB-p65 and the recovery rates were calculated by comparing the measured value to the expected amount of NFκB-p65 in samples.
        Matrix Recovery range Average
        serum(n=5) 90-107% 98%
        EDTA plasma(n=5) 93-107% 100%
        Heparin plasma(n=5) 85-97% 91%

        線性

        The linearity of the kit was assayed by testing samples spiked with appropriate concentration of NFκB-p65 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
