QuicKey Pro Mouse IL-18 (Interleukin 18) ELISA Kit

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Mouse IL-18. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Mouse IL-18 are added to the micro ELISA plate wells. Mouse IL-18 in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Mouse IL-18.Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Mouse IL-18. The concentration of Mouse IL-18 in the samples is then determined by comparing the OD of the samples to the standard curve.
