This immunoassay kit allows for the in vitro quantitative determination of canine Interleukin 1β,IL-1β concentrations in cell culture supernates, serum, plasma and other biological fluids.
The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL-1β. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for IL-1β. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain IL-1β, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm 2 nm. The concentration of IL-1β in the samples is then determined by comparing the O.D. of the samples to the standard curve.
