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 Human NF-κBp105. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human 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 Human 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 Human NF-κBp105 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 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)	80-109%	95%
EDTA plasma(n=5)	88-123%	106%
Heparin plasma(n=5)	85-91%	88%

線性

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.
