Human sCD21 ELISA Kit
HumanThe kit is for the quantitative level of sCD21 in the sample, adopt purified Human sCD21 to coat microtiter plate,
make solid-phase antibody, then add sCD21 to wells, Combine sCD21 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 sCD21 in the
samples is then determined by comparing the O.D. of the samples to the standard curve.
