The Rat POSTN/OSF-2 (Periostin) ELISA Kit is specifically designed for the accurate measurement of periostin levels in rat samples, including serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring precise and consistent results for various research applications.Periostin, also known as osteoblast-specific factor 2 (OSF-2), is a crucial protein that plays a key role in tissue development and repair. It is involved in the regulation of cell adhesion, migration, and proliferation, making it a valuable biomarker for studying various physiological and pathological processes.
With the Rat POSTN/OSF-2 ELISA Kit, researchers can effectively investigate the role of periostin in conditions such as fibrosis, cancer, and cardiovascular diseases. Its reliable performance and easy-to-use format make it an essential tool for advancing research in these areas and potentially developing new therapeutic strategies.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat 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 Rat 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 Rat 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 Rat POSTN/OSF-2. You can calculate the concentration of Rat POSTN/OSF-2 in the samples by comparing the OD of the samples to the standard curve.
