The Rat Cardiac Troponin T, Type 2 (TNNT2) ELISA Kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of TNNT2 in rat serum, plasma and other biological fluids.
Catalog #028637
Detection Range15.6-1,000pg/ml
Sensitivity< 5.4pg/ml
PrecisionIntra-Assay: CV<10%
Inter-Assay: CV<12%
Test PrincipleThe microtiter plate provided in this kit has been pre-coated with an antibody specific to TNNT2. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to 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 TNNT2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of TNNT2 in the sample is then determined by comparing the O.D. of the sample to the standard curve.
