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 cTnT/TNNT2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse cTnT/TNNT2. 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 cTnT/TNNT2, 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 cTnT/TNNT2 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 cTnT/TNNT2 and the recovery rates were calculated by comparing the measured value to the expected amount of cTnT/TNNT2 in samples.
Matrix Recovery range Average
serum(n=5) 80-95% 87%
EDTA plasma(n=5) 78-92% 85%
Heparin plasma(n=5) 78-96% 87%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of cTnT/TNNT2 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) 92-104% 82-96% 95-102% 87-98%
EDTA plasma(n=5) 87-98% 92-104% 82-96% 95-102%
Heparin plasma(n=5) 89-97% 85-94% 79-96% 85-99%
