Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of MCF-7 cells using CEA/CD66e Recombinant antibody (83653-5-RR)

    WB analysis of MCF-7 using 83653-5-RR (same clone as 83653-5-PBS)

    MCF-7 cells were subjected to SDS PAGE followed by western blot with 83653-5-RR (CEA antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83653-5-PBS in a different storage buffer formulation.

  • Western Blot (WB) analysis of human saliva using CEA/CD66e Recombinant antibody (83653-5-RR)

    WB analysis of human saliva using 83653-5-RR (same clone as 83653-5-PBS)

    human saliva were subjected to SDS PAGE followed by western blot with 83653-5-RR (CEA antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83653-5-PBS in a different storage buffer formulation.

  • Immunohistochemistry (IHC) staining of human ovary cancer tissue using CEA/CD66e Recombinant antibody (83653-5-RR)

    IHC staining of human ovary cancer using 83653-5-RR (same clone as 83653-5-PBS)

    Immunohistochemical analysis of paraffin-embedded human ovary cancer tissue slide using 83653-5-RR (CEA antibody) at dilution of 1:1000 (under 40x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 83653-5-PBS in a different storage buffer formulation.

Background Information

Carcinoembryonic antigen (CEA), also known as CEACAM5 or CD66e, is a cell surface glycoprotein belonging to the immunoglobulin superfamily, mainly serving as a cell adhesion molecule mediating intercellular contact by both homophilic and heterophilic binding (PMID: 21731662). CEA inhibits anoikis and plays a role in tumorigenesis and metastasis. CEA has been found to be overexpressed in a wide variety of human cancers, including colon, breast, and lung (PMID: 17167768). CEA is a tumor marker and is routinely exploited for diagnosis.
