Produktbeschreibung

The Interleukin 35 (IL-35) BioAssay(TM) ELISA Kit is a sandwich ELISA for the in vitro quantitative determination of IL-35 concentrations in human serum, plasma and other biological fluids. Detection Range: 15.63-1000pg/ml Sensitivity: 9.38pg/ml Precision: Intra-Assay %CV: <10% Inter-Assay %CV: <10% Specificity: Recognizes human IL-35. No significant cross-reactivity or interference between human IL-35 and analogues was observed. Test Principle: The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL-35. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to IL-35. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Free components are washed away. The substrate solution is added, only those wells that contain IL-35, biotin-conjugated antibody and enzyme-conjugated Avidin will apear blue in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450nm 2nm. The OD value is proportional to the concentration of human IL-35. The concentration of IL-35 in the sample is then determined by comparing the O.D. of the sample to the standard curve.
