Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Pig Anti-SST protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Pig Anti-SST. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. 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 Pig Anti-SST 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 Anti-SST and the recovery rates were calculated by comparing the measured value to the expected amount of Anti-SST in samples.
Matrix Recovery range Average
serum(n=5) 95-107% 101%
EDTA plasma(n=5) 90-105% 97%
Heparin plasma(n=5) 97-105% 101%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Anti-SST 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) 88-97% 78-96% 80-99% 89-97%
EDTA plasma(n=5) 93-104% 87-96% 82-95% 78-99%
Heparin plasma(n=5) 95-104% 93-105% 82-101% 91-103%
