Application

Anti-POSTN antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Actions biochimiques/physiologiques

POSTN (Periostin, osteoblast specific factor) is an oncofetal protein consisting of four internal repeat domains. It is a vitamin K dependent protein expressed in mesenchymal stromal cells. Specifically, it is highly expressed in the normal fetal tissues including aorta, stomach, lower gastrointestinal tract, placenta, uterus, and breast except normal ovarian tissues. It has been first identified in the osteoblast cells with heparin binding ability. In ovarian epithelial cells, it drives the cellular adhesion of α(V)β(3) integrin, but not β(1) integrins, as a ligand for promoting the cell motility. It has been suggested that carboxylated POSTN, produced by bone-derived cells of mesenchymal lineage may play an important role in extracellular matrix mineralization.

Caractéristiques et avantages

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
