Monoclonal Mouse Anti-Human
Carcinoembryonic Antigen (CEA)
Clone II-7
Monoclonal antibodies to CEA have been classified into five essentially non-interacting epitope groups, designated Gold 1 to 5. Dako Anti-CEA, clone II-7, belongs to epitope group Gold 1 and shows a high degree of CEA specificity (1).
CEA is a clinically important marker for adenocarcinomas, notably in the gastrointestinal tract, including colonic and pancreatic carcinomas. The characteristic CEA expression of secretory meningiomas is labeled by the antibody (2). Antibodies to CEA may also be useful for the identification of medullary carcinoma of the thyroid (3).

previousnext
Colon adenocarcinoma. The majority of the neoplastic cells show a distinct and predominantly cytoplasmic staining reaction.
Clinical application for IR622/IS622. For identification of carcinoembryonic antigen (CEA)-positive glycocalyx surface of gastrointestinal cells and colon carcinoma.
Medullary carcinoma of thyroid. The neoplastic cells show a strong membranous and cytoplasmic staining reaction.
Clinical application for IR622/IS622. For identification of carcinoembryonic antigen (CEA)-positive glycocalyx surface of gastrointestinal cells and colon carcinoma.
Colon. The epithelial cells of the appendical mucosa show a moderate to strong cytoplasmic staining reaction. At the luminal surface and the glycocalyx, the staining is stronger than in cells in the basal layer. Both compartments should be demonstrated.
Recommended control for IR622/IS622. Appendix/Colon.
Tonsil. Focally, the squamous epithelial cells show a weak to moderate cytoplasmic staining reaction. If well preserved, 2/3 of the upper layer should be demonstrated.
Recommended control for IR622/IS622. Appendix/Colon/Tonsil.

Intended Use
For in vitro diagnostic use.
Monoclonal Mouse Anti-Human Carcinoembryonic Antigen (CEA), Clone II-7, is intended for use in immunohistochemistry. The antibody labels the CEA-positive glycocalyx surface of gastrointestinal cells and is a useful tool for the identification of colon carcinomas (1). In addition, the characteristic CEA expression of secretory meningiomas, is labeled by the antibody (2). Differential identification is aided by the results from a panel of antibodies. Interpretation must be made within the context of the patient´s clinical history and other diagnostic tests by a qualified pathologist.

Immunogen
Purified human CEA from liver metastasis of lung adenocarcinoma (3).
Specificity
In ELISA, the antibody reacts with CEA preparations from both colo-rectal carcinomas, lung andenocarcinomas and the colon carcinoma cell line LS 174T, whereas the antibody does not cross-react with isolated CEA-related antigens, e.g. NCA-55, NCA-95, NCA-160 and BGP I (3). Based on ELISA, using reduced, carboxymethylated and Smith degraded CEA, the antibody is predicted to react with a conformation dependent epitope, in which the carbohydrate structures of the CEA glycoprotein are involved (3).
Using solid-phase competitive immunoassays, monoclonal antibodies to CEA have been classified into five essentially non-interacting epitope groups called GOLD 1-5. Monoclonal antibodies with a high degree of CEA specificity generally belong to epitope groups GOLD 1 or 3. Monoclonal Mouse Anti-Human Carcinoembryonic Antigen (CEA), Clone II-7, belongs to epitope group GOLD 1 (7).
