Background of Periostin/OSF-2

POSTN (Periostin), also known as PN or OSF2, is a protein that in humans is encoded by the POSTN gene. The International Radiation Hybrid Mapping Consortium mapped the POSTN gene to chromosome 13. It was found that purified recombinant PN supported adhesion of ovarian epithelial cells. And periostin was overexpressed by the majority of human primary breast cancers examined. Transfected tumor cell lines overexpressing periostin showed accelerated growth and angiogenesis as xenografts in immunocompromised animals. It was showed that extracellular periostin induced reentry of differentiated mammalian cardiomyocytes into the cell cycle.

4 Customer Q&As for Anti-Periostin/Postn Antibody Picoband™


We bought anti-Periostin/Postn antibody for ELISA on pubmed:8363580} in a previous experiment. I am using rat, and I plan to use the antibody for IHC next. My question regards examining pubmed:8363580} as well as pubmed:8363580} rc placenta eco:0000269 in our next experiment. Do you have any suggestion on which antibody would work the best for IHC?

I looked at the website and datasheets of our anti-Periostin/Postn antibody and it seems that A01378 has been tested on rat in both ELISA and IHC. Thus A01378 should work for your application. Our Boster satisfaction guarantee will cover this product for IHC in rat even if the specific tissue type has not been validated. We do have a comprehensive range of products for IHC detection and you can check out our website to find out more information about them.

Our lab were satisfied with the WB result of your anti-Periostin/Postn antibody. However we have observed positive staining in osteosarcoma {eco:0000269 golgi apparatus using this antibody. Is that expected? Could you tell me where is POSTN supposed to be expressed?

According to literature, osteosarcoma eco:0000269 does express POSTN. Generally POSTN expresses in golgi apparatus. Regarding which tissues have POSTN expression, here are a few articles citing expression in various tissues:
Liver, Pubmed ID: 19159218, 24275569
Osteosarcoma, and Placenta, Pubmed ID: 8363580
Periodontal ligament, Pubmed ID: 15057823

We are currently using anti-Periostin/Postn antibody A01378 for mouse tissue, and we are well pleased with the IHC results. The species of reactivity given in the datasheet says mouse, rat. Is it true that the antibody can work on zebrafish tissues as well?

The anti-Periostin/Postn antibody (A01378) has not been validated for cross reactivity specifically with zebrafish tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in zebrafish you can get your next antibody for free. Please contact me if I can help you with anything.
