Rat TTR(Transthyretin) ELISA Kit

Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain Assay Type: Sandwich. Sensitivity: 2.1 µg/mL. Standard: 500 µg/mL. Detection range: 7.82-500 µg/mL. Sample type: Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.. Assay length: 3.5h. Research Field: Enzyme & Kinase,Tumor immunity,Infection immunity,Hormone metabolism,. 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 TTR. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat TTR. 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 TTR, 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 TTR in the samples is then determined by comparing the OD of the samples to the standard curve.
