General description

Anti-CEA is employed essentially as a tool to assist in the distinction between adenocarcinoma and epithelioid malignant mesotheliomas, along with other markers such as those against calretinin, CK 5&6, CD15, HBME-1, MOC-31, and Ber-EP4. Another suggested use of anti-CEA is to immunophenotype various metastatic adenocarcinomas as a means of identifying their origin within a panel of different markers. Anti-CEA positivity is seen in adenocarcinomas from the lung, colon, stomach, esophagus, pancreas, gallbadder, urachus, salivary gland, ovary, and endocervix. Polyclonal anti-CEA is useful in staining hepatocellular carcinoma in a canalicular pattern.


CEA Positive Control Slides, Product No. 236S, are available for immunohistochemistry (formalin-fixed, paraffin-embedded sections).
