AffiELISA® Rabbit IGF1 Kit: Ultra-Sensitive Insulin Like Growth Factor 1 ELISA Detection

The AffiELISA® Rabbit IGF1 Kit uses Sandwich enzyme immunoassay. The provided microtiter plate comes pre-coated with an antibody specific to Insulin Like Growth Factor 1 (IGF1) . To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Insulin Like Growth Factor 1 (IGF1) 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 Insulin Like Growth Factor 1 (IGF1) , 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 Insulin Like Growth Factor 1 (IGF1) in the samples can be determined.
