Principle of test
The kit assay Bovine IgM level in the sample,use Purified Bovine IgM antibody to coat microtiter plate wells, make solid-phase antibody, then add IgM to wells, Combined IgM antibody which With HRP labeled , become 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 sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of IgM in the samples is then determined by comparing the O.D. of the samples to the standard curve.
