Principle of the Assay |
This ELISA kit is applied to the double antibody sandwich Enzyme Linked Immunosorbent Assay to detect the concentration of human IgA in samples. The microtiter plate has been pre-coated with goat anti-human antibody, standards or samples are then added to the microtiter plate wells and IgA if present, will bind to the antibody pre-coated wells under specific conditions. Then wash the plate to remove unbound substances, add the HRP-conjugated goat anti-human antibody, and incubate at room temperature to form a double-antibody sandwich complex with the coated antibody, human IgA, and detection antibody. Then a TMB substrate solution is added to the wells to incubate. TMB substrate solution turns blue after the oxidation of HRP, and finally turns to yellow immediately after adding the stop solution. Color of TMB substrate positively correlated with total IgA bound in the initial steps. The color is measured by spectrophotometrically with wavelength of 450nm. The concentration of human IgA in samples is then determined by comparing the O.D. of the samples to the standard curve. |
