This Thrombin/Antithrombin Complex (TAT) BioAssay™ ELISA Kit is a sandwich ELISA for the in vitro quantitative determination of TAT concentrations in porcine serum, plasma and other biological fluids.||Detection Range:|78.13-5000pg/ml||Sensitivity:|46.88pg/ml||Precision:|Intra-Assay %CV: <10%|Inter-Assay %CV: <10%||Specificity:|Recognizes porcine TAT. No significant cross-reactivity or interference between porcine TAT and analogues was observed.||Test Principle:|The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to porcine TAT. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for porcine TAT and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain porcine TAT, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (O.D.) is measured spectrophotometrically at a wavelength of 450nm ± 2nm. The O.D. value is proportional to the concentration of porcine TAT. You can calculate the concentration of porcine TAT in the samples by comparing the O.D. of the samples to the standard curve.|||Kit Components:|*530081A: Microtiter Strips, 1x96 wells, Pre-coated; ready to use|*530081B: Standard, 2x1vial |530081C: Standard Diluent, 1x20ml|*530081D: Biotin Detection, 100X, 1x120ul |*530081E: HRP Conjugate, 100X, 1x120ul |530081F: Biotin Detection Diluent, 1x14ml|530081G: HRP Diluent, 1x14ml|530081H: Substrate, 1x10ml|530081K: Stop Solution, 1x10ml|530081L: Wash Buffer, 25X, 1x30ml ||Storage and Stability:|Store *530081A, *530081B, *530081D and *530081E at -20°C.
