Human IL28B (Interleukin 28B) ELISA kit

This kit applies sandwich ELISA method for the quantitative detection of IL28B (Interleukin 28B) in human samples. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL28B. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL28B. 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 Human IL28B, 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 Human IL28B in the samples is then determined by comparing the OD of the samples to the standard curve.
