Human Interleukin 18,IL-18 ELISA KIT
Purpose
This kit allows for the determination of IL-18 concentrations in Human serum, blood plasma, and other biological fluids.
Principle of the assay
The kit assay Human IL-18 level in the sample，use Purified Human IL-18 antibody to coat microtiter plate wells, make solid-phase antibody, then add IL-18 to wells, Combined IL-18 antibody which With HRP labeled，become antibody-antigen- enzyme-antibody complex, after washing Completely, Add TMB substrate solution, TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of IL-18 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
