Human 25-Hydroxy vitamin D3 (25HVD3) ELISA Kit
HumanThe kit is for the quantitative level of 25-OH-D in the sample, adopt purified Human 25-OH-D to coat microtiter
plate, make solid-phase antibody, then add 25-OH-D to wells, Combine 25-OH-D 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 25-OH-D in the
samples is then determined by comparing the O.D. of the samples to the standard curve.
