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 NF-κBp105. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse NF-κBp105. 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 NF-κBp105, 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 NF-κBp105 in the samples is then determined by comparing the OD of the samples to the standard curve.

Precision

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.

Recovery

Matrices listed below were spiked with certain level of recombinant NF-κBp105 and the recovery rates were calculated by comparing the measured value to the expected amount of NF-κBp105 in samples.
Matrix Recovery range Average
serum(n=5) 85-99% 92%
EDTA plasma(n=5) 78-92% 85%
Heparin plasma(n=5) 78-90% 84%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of NF-κBp105 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) 88-102% 96-107% 89-103% 79-95%
EDTA plasma(n=5) 81-94% 78-90% 83-95% 86-97%
Heparin plasma(n=5) 80-94% 90-99% 87-103% 83-96%
