Rat TSP-1(Thrombospondin-1) ELISA Kit

Assay Type: Sandwich. Sensitivity: 0.46 ng/mL. Standard: 100 ng/mL. Detection range: 1.56-100 ng/mL. Sample type: Plasma. Assay length: 3.5h. Research Field: Infection immunity,Hematology,. 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 TSP-1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat TSP-1. 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 TSP-1, 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 TSP-1 in the samples is then determined by comparing the OD of the samples to the standard curve.
