AffiELISA® Human GIP Kit: High Sensitivity Gastric Inhibitory Polypeptide ELISA Detection

The AffiELISA® Human GIP Kit uses competitive inhibition enzyme immunoassay technique. The provided microtiter plate comes pre-coated with Gastric Inhibitory Polypeptide (GIP) protein. To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Gastric Inhibitory Polypeptide (GIP) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. Afterward, the TMB substrate solution is added, initiating an enzyme-substrate reaction. To conclude the reaction, a sulphuric acid solution is introduced, causing a color change that can be measured spectrophotometrically at a wavelength of 450nm ± 10nm. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Gastric Inhibitory Polypeptide (GIP) in the samples can be determined.
