Specificity & Comments

It recognizes a protein of 54kDa, which is identified antitrypsin (AAT). The immunohistochemical staining of AAT is useful in identification of benign and malignant hepatic tumors and yolk sac carcinomas. Positive staining for AAT is also used in detection of benign and malignant lesions of histiocytic nature. This antibody is may also useful tool in the screening of patients with cryptogenic cirrhosis or other forms of liver disease with fibrosis of uncertain origin.

Known Applications & Suggested Dilutions

Flow Cytometry (0.5-1ug/million cells)
Immunofluorescence (0.5-1ug/ml)
western Blotting (0.5-1.0ug/ml)
Western Blotting (0.5-1.0ug/ml)
Immunohistology (Formalin-fixed) (0.5-1ug/ml for 30 minutes at RT)
(Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes)
Optimal dilution for a specific application should be determined.

Positive Control

HepG2 Cells. Tonsil, Hepatocellular Carcinoma or Histiocytoma.
