Clone Host Grade Applications
Polyclonal Rabbit Highly Purified B IP IH
Carcinoembryonic antigen (CEA), which is synthesized during development in the fetal gut, and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. Anti-CEA is reportedly useful in identifying the origin of various metastatic adenocarcinomas and in distinguishing pulmonary adenocarcinomas (60-70% are CEA+) from pleural mesotheliomas (rarely or weakly CEA+).
Catalog #C1300-08
