Human IA-2 Ab (Insulinoma associated antigen 2 Autoantibody) ELISA kit

This kit applies sandwich ELISA method for the quantitative detection of IA-2 Ab (Insulinoma associated antigen 2 Autoantibody) in human samples. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IA-2 Ab. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IA-2 Ab. 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 Human IA-2 Ab, 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 Human IA-2 Ab in the samples is then determined by comparing the OD of the samples to the standard curve.
