产品说明
一般描述
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.
免疫原
Elafin precursor recombinant protein epitope signature tag (PrEST)
应用
Anti-PI3 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). 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.
生化/生理作用
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.
特点和优势
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:
