| General description: | Alpha-1-Antitrypsin is a protease inhibitor from the serpin superfamily, which inhibits a number of protease enzymes from inflammatory cells. It is an acute-phase plasma protein predominantly produced in hepatocytes, although it is also made in enterocytes and some mononuclear white blood cells. Alpha-1-antitrypsin immunohistochemistry is used to detect the accumulation of alpha-1-antitrypsin in hepatic lesions and histiocytic tumors. The immunohistochemical staining of Alpha-1-Antitrypsin is considered to be very useful in the study of inherited AAT deficiency, benign and malignant hepatic tumors, and yolk sac carcinomas. Positive staining for A-1-Antitrypsin may also be used in the detection of benign and malignant lesions of a histiocytic nature. The sensitivity and specificity of the results have made this antibody a useful tool in the screening of patients with cryptogenic cirrhosis or other forms of liver disease with portal fibrosis of uncertain etiology. |
