Human Immunoglobulin G,IgG ELISA Kit

FOR RESEARCH USE ONLY. Not FOR CLINICAL DIAGNOSIS USE. Purpose This kit allows for the determination of  IgG concentrations in Human serum, blood plasma, and other biological fluids. Principle of the assay The kit assay Human IgG  level in the sample，use Purified Human IgG  antibody to coat microtiter plate wells, make solid-phase antibody, then add IgG  to wells, Combined IgG  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 IgG  in the samples is then determined by comparing the O.D. of the samples to the standard curve.
