Human Troponin T1 / TNT ELISA Kit (A311337) employs the sandwich enzyme immunoassay technique for the quantitative measurement of human Troponin T1 / TNT in An antibody specific for Troponin T1 / TNT has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the Troponin T1 / TNT present in each sample is bound to the wells by the immobilized antibody. Biotinylated Anti-Troponin T1 / TNT Antibody, which also binds the Troponin T1 / TNT present in each sample, and Streptavidin-HRP, which binds the Biotinylated Anti-Troponin T1 / TNT Antibody, are added and the microtiter plate is incubated. Following incubation, unbound Biotinylated Anti-Troponin T1 / TNT Antibody and unbound Streptavidin-HRP are removed by washing, and two substrate solutions are added to the wells. Color develops in proportion to the amount of Troponin T1 / TNT captured in each well. The color development is stopped by addition of stop solution which changes the color from blue to yellow and the intensity of the color is then measured. The concentration of Troponin T1 / TNT in the samples can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
