CEA Antibody / Carcinoembryonic Antigen

• Catalog Number: orb749454
• Category: Antibodies
• Description: This antibody recognizes proteins of 80-200kDa, identified as different members of CEA family. CEA is synthesized during development in the fetal gut and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. This mAb reacts with nonspecific cross-reacting antigen (NCA). It shows no reaction with a variety of normal tissues and is suitable for staining of formalin/paraffin tissues. CEA is not found in benign glands, stroma, or malignant prostatic cells. Antibody to CEA is useful in detecting early foci of gastric carcinoma and in distinguishing pulmonary adenocarcinomas (60-70% are CEA+) from pleural mesotheliomas (rarely or weakly CEA+). Anti-CEA positivity is seen in adenocarcinomas from the lung, colon, stomach, esophagus, pancreas, gallbadder, urachus, salivary gland, ovary, and endocervix.
• Clonality: Monoclonal
• Species/Host: Mouse
• Isotype: Mouse IgG2b, kappa
• Conjugation: Unconjugated
• Reactivity: Human
• Immunogen: Purified human protein was used as the immunogen for the CEA antibody.
• UniProt ID: P06731
• Tested applications: IHC-P
• Dilution range: Immunohistochemistry (FFPE): 0.25-0.5ug/ml for 30 min at RT (1) (2)
• Application notes: Optimal dilution of the CEA antibody to be determined by the researcher.1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
