Human Carbohydrate antigen19-9,CA19-9 ELISA Kit
The kit is for the quantitative level of CA19-9 in the sample, adopt purified Human CA19-9 to coat microtiter plate, make
solid-phase antibody, then add CA19-9 to wells, Combine CA19-9 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 CA19-9 in the samples is then determined by comparing the O.D. of the
samples to the standard curve.
