AffiELISA® Rat TCN2 Kit: Max Sensitivity Transcobalamin II, Macrocytic Anemia ELISA Detection

The AffiELISA® Rat TCN2 Kit uses Sandwich enzyme immunoassay. The provided microtiter plate comes pre-coated with an antibody specific to Transcobalamin II, Macrocytic Anemia (TCN2) . To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Transcobalamin II, Macrocytic Anemia (TCN2) 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 Transcobalamin II, Macrocytic Anemia (TCN2) , 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 Transcobalamin II, Macrocytic Anemia (TCN2) in the samples can be determined.
