AffiELISA® Cattle CSN1 Kit: Max Sensitivity Casein Alpha ELISA Detection

The AffiELISA® Cattle CSN1 Kit uses Sandwich enzyme immunoassay. The provided microtiter plate comes pre-coated with an antibody specific to Casein Alpha (Cattle CSN1) . To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Casein Alpha (Cattle CSN1) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. After TMB substrate solution is added, only those wells that contain Casein Alpha (Cattle CSN1) , 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. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Casein Alpha (Cattle CSN1) in the samples can be determined.
