PRINCIPLE OF TEST
The kit is for the quantitative level of TNF-α in the sample, adopt purified Mouse TNF-α to coat microtiter plate, make solid-phase antibody, then add TNF-α to wells, Combine TNF-α 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 TNF-α 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: 25ng/L -500ng/L
