General description
Peptidase inhibitor 3 (PI3) is an endogenous serine protease inhibitor which is expressed in the epithelium of the gastrointestinal tract. It is a 9.9kDa protein consisting of 95 amino acids. PI3 belongs to the chelonianin family of proteins and the gene encoding it is localized on chromosome 20.
Immunogen
Elafin precursor recombinant protein epitope signature tag (PrEST)
Application
Anti-PI3 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.
Biochem/physiol Actions
Peptidase inhibitor 3 (PI3) has an inhibitory effect against various elastases and proteinases. It is a substrate of tissue transglutaminase 2 (TG-2), which has a cross-linking activity. In cardiovascular, respiratory and colonic inflammation, PI3 shows anti-inflammatory effects and barrier modifying properties. It is called an “alarm” antiproteinase, since it is secreted at the sites of inflammation by the same stimuli that causes initial inflammatory response. It has been shown that PI3 is overexpressed in basal-like breast cancer tumors and high-grade serous ovarian carcinoma. PI3 may also act as a marker of renal inflammation and injury.
Features and Benefits
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:
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.

Elafin (peptidase inhibitor 3 [PI3]) and its biologically active precursor, pre-elafin, are neutrophil serine proteinase inhibitors with an important role in preventing excessive tissue injury during inflammatory events. Recently, we reported an association between single-nucleotide polymorphism (SNP) rs2664581 in the
