Overview 文獻(xiàn)

Product name: Rat hs-cTnT(High Sensitivity Cardiac Troponin T) ELISA Kit
Reactivity: Rat
Alternative Names: High Sensitivity Cardiac Troponin T
Assay Type: Sandwich
Sensitivity: 5.2 pg/mL
Standard: 1000 pg/mL
Detection Range: 15.63-1000 pg/mL
Sample Type: serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids
Assay Length: 3.5h
Research Area: Cardiovascular biology
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 Rat hs-cTnT. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat hs-cTnT. 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 Rat hs-cTnT, 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 Rat hs-cTnT 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 hs-cTnT and the recovery rates were calculated by comparing the measured value to the expected amount of hs-cTnT in samples.
Matrix Recovery range Average
serum(n=5) 85-97% 91%
EDTA plasma(n=5) 79-93% 86%
Heparin plasma(n=5) 82-95% 88%

線性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of hs-cTnT 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) 79-96% 85-99% 79-93% 89-97%
EDTA plasma(n=5) 85-94% 87-101% 89-99% 85-95%
Heparin plasma(n=5) 86-94% 93-102% 89-97% 85-94%
