SERPINA1 (serpin peptidase inhibitor, clade A, member 1), also called a1-antitrypsin, is an acute-phase glycoprotein, which belongs to the serpin superfamily. It is predominantly found in the plasma, and is secreted by hepatocytes. This gene is localized to human chromosome 14q32.1, and is composed of four coding and three non-coding exons.
Synonyms: Anti-Alpha-1 protease inhibitor; Anti-Alpha-1-antiproteinase; Anti-Alpha-1-antitrypsin precursor; Anti-SPAAT
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: a-1 Antitrypsin (A1AT or AAT) is a serine proteinase inhibitor with potent anti-inflammatory, anti-apoptotic, antimicrobial and cytoprotective activities. In humans, it could be a potential novel therapeutic drug for the protection against neurodegeneration after ischemic stroke. Its deficiency is associated with an increased risk for lung and liver disease.
