This Insulin enzyme linked immunosorbent assay (ELISA) applies a technique called a quantitative sandwich immunoassay. The microtiter plate has been pre-coated with an Anti-Insulin Antibody. Standards or samples are then added to the microtire plate wells and Insulin, if present, will bind to the antibody pre-coated on the wells. In order to quantify the amount of Insulin present in the sample, Anti-Insulin Antibody (HRP) is added to each well to "sandwich" the Insulin immobilised on the plate. The microtiter plate then undergoes incubation, followed by thorough washing of the wells to remove all unbound components. Next, a TMB (3,3',5,5' tetramethyl-benzidine) substrate solution is added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain Insulin will exhibit a change in colour. The enzyme-substrate reaction is terminated by the addition of a stop solution and the colour change is measured spectrophotometrically at a wavelength of 450nm ± 2nm.
