CEA Antibody / Carcinoembryonic Antigen

• Catalog Number: orb385826
• Category: Antibodies
• Description: CEA is synthesized during development in the fetal gut and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. 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+).

• UniProt ID: P06731
• Storage: Store the CEA antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
• Buffer/Preservatives: 0.2 mg/ml in 1X PBS with 0.1 mg/ml rAlbumin (US sourced) and 0.05% sodium azide
• Note: For research use only
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the CEA antibody to be titered up or down for optimal performance.1. 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.2. 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.
• Expiration Date: 12 months from date of receipt.
