Sample Type:Serum, plasma, tissue homogenates and cell lysatesIntended Use:For the quantitative determination of endogenic rat free tri-iodothyronine indes (Free-T3) concentrations in serum, plasma, tissue homogenates and cell lysates. Sensitivity:0.38pmol/L.Range:2-32pmol/LSpecificity:This assay has high sensitivity and excellent specificity for detection of rat Free-T3. No significant cross-reactivity or interference between rat Free-T3 and analogues was observed.Test Principle:This BioAssay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with an antibody specific to T3. Standards or samples are added to the appropriate microtiter plate wells with Biotin-conjugated T3. A competitive inhibition reaction is launched between T3 (Standards or samples) and Biotin-conjugated T3 with the pre-coated antibody specific for T3. The more T3 in samples, the less antibody bound by Biotin-conjugated T3. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Substrate solution is added to the wells and the color develops in opposite to the amount of Free-T3 in the sample. The color development is stopped and the intensity of the color is measured.
