Cattle IGFBP4(Insulin Like Growth Factor Binding Protein 4) ELISA Kit

Description: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Insulin Like Growth Factor Binding Protein 4(Cattle IGFBP4) protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Insulin Like Growth Factor Binding Protein 4(Cattle IGFBP4). Next,Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. 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 Insulin Like Growth Factor Binding Protein 4(Cattle IGFBP4) in the samples is then determined by comparing the OD of the samples to the standard curve.
