Overview

Product name:	Human hs-cTnI (High Sensitivity Cardiac Troponin I) Microsample ELISA Kit
Reactivity:	Human
Alternative Names:	High Sensitivity Cardiac Troponin I
Assay Type:	Sandwich
Sensitivity:	9.8 pg/mL
Standard:	2000 pg/mL
Detection Range:	31.25-2000 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 Human hs-cTnI. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human hs-cTnI. 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 hs-cTnI, 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 hs-cTnI 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-cTnI and the recovery rates were calculated by comparing the measured value to the expected amount of hs-cTnI in samples.

Matrix	Recovery range	Average
serum(n=5)	91-111%	101%
EDTA plasma(n=5)	88-110%	99%
Heparin plasma(n=5)	94-104%	99%

线性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of hs-cTnI and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
