  • Product overview

    Abcam’s Carcino Embryonic Antigen in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Carcino Embryonic Antigen in Human serum.

    A 96-well plate has been precoated with anti-Carcino Embryonic Antigen antibodies. Samples and standards and are added to the wells, where Carcino Embryonic Antigen in the sample and standards binds to the precoated antibody. Added Anti-Carcino Embryonic Antigen-HRP conjugate binds to the antibody-Carcino Embryonic Antigen complex. After incubation, the wells are washed to remove unbound material and TMB substrate is then added which is catalyzed by HRP to produce blue coloration. The reaction is terminated by addition of Stop Solution which stops the color development and produces a color change from blue to yellow. The intensity of signal is directly proportional to the amount of Carcino Embryonic Antigen in the sample and the intensity is measured at 450 nm.

  • PlatformMicroplate


  • RelevanceCarcino Embryonic Antigen (CEA) is synthesised during development in the fetal gut, and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. Antibodies to CEA are useful in identifying the origin of various metastatic adenocarcinomas and in distinguishing pulmonary adenocarcinomas (60 to 70% are CEA+) from pleural mesotheliomas (rarely or weakly CEA+).

Thank you for your e-mail. We do not have experience with the determination of CEA in mouse with our CEA ELISA, ab108635. It could work but I cannot give you a guarantee.

In this case I would be happy to offer the same testing discount promot...
