Recovery

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)	82-94%	88%
EDTA plasma(n=5)	85-97%	91%
Heparin plasma(n=5)	81-93%	87%

Linearity

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)	92-101%	87-98%	85-92%	79-96%
EDTA plasma(n=5)	88-97%	90-99%	87-103%	82-97%
Heparin plasma(n=5)	85-94%	90-99%	82-101%	91-102%

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.

Usage Notes

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 Goat IL-12p40. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Goat 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 Goat 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 Goat IL-12p40 in the samples is then determined by comparing the OD of the samples to the standard curve.
