Assay Methodology: Quantitative Sandwich Immunoassay

Colorimetric

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Serpin Peptidase Inhibitor, Clade B, Member 4 (SERPINB4). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Serpin Peptidase Inhibitor, Clade B, Member 4 (SERPINB4). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Serpin Peptidase Inhibitor, Clade B, Member 4 (SERPINB4), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Serpin Peptidase Inhibitor, Clade B, Member 4 (SERPINB4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
