Human POSTN/OSF-2 (Periostin) ELISA Kit

Human POSTN/OSF-2 (Periostin) ELISA KitThe Human POSTN OSF 2 (Periostin) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Human POSTN OSF 2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human POSTN OSF 2 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each

The Human POSTN/OSF-2 (Periostin) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human POSTN/OSF-2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human POSTN/OSF-2 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human POSTN/OSF-2, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human POSTN/OSF-2. You can calculate the concentration of Human POSTN/OSF-2 in the samples by comparing the OD of the samples to the standard curve.
