The kit is for the quantitative level of IL-23 in the sample, adopt purified human IL-23 to coat microtiter plate, make solid-phase antibody, then add IL-23 to wells, Combine IL-23 antibody with labeled HRP to form 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 stop solution and the color change is measured at a wavelength of 450 nm. The concentration of IL-23 in the samples is then determined by comparing the O.D. of the samples to the standard curve. 

DETECTION RANGE

Detection range of the kit is: 15ng/L-400ng/L
