Principle of the Assay |
This ELISA kit is applied to the double antibody sandwich Enzyme Linked Immunosorbent Assay to detect the concentration of PA in samples. The microtiter plate has been pre-coated with chicken anti-PA antibody , standards or samples are then added to the microtiter plate wells and PA if present, will bind to the antibody pre-coated wells under specific conditions. After washing, then a Horseradish Peroxidase(HRP)-conjugated detection rabbit anti-PA antibody is added to the wells, under 37℃ incubation, to form a precoated antibody-PA-detection antibody sandwich complex. 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 PA bound in the initial steps. The color is measured by spectrophotometrically with wavelength of 450nm. The concentration of PA in samples is then determined by comparing the O.D. of the samples to the standard curve. |
