        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 IL-12p40. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse IL-12p40. 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 IL-12p40, 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 IL-12p40 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 IL-12p40 and the recovery rates were calculated by comparing the measured value to the expected amount of IL-12p40 in samples.
        Matrix Recovery range Average
        serum(n=5) 94-105% 98%
        EDTA plasma(n=5) 82-94% 88%
        Heparin plasma(n=5) 83-99% 95%

        線性

        The linearity of the kit was assayed by testing samples spiked with appropriate concentration of IL-12p40 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
        Matrix 1:2 1:4 1:8 1:16
        serum(n=5) 91-99% 83-89% 88-104% 97-103%
        EDTA plasma(n=5) 85-95% 79-96% 89-101% 85-97%
        Heparin plasma(n=5) 86-96% 93-104% 89-97% 85-94%
