The kit is for the quantitative level of sTfR in the sample, adopt purified Human sTfR to coat microtiter plate, make

solid-phase antibody, then add sTfR to wells, Combine sTfR 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 sTfR in the samples is then determined by comparing

the O.D. of the samples to the standard curve
