Validation Data Gallery

• 

  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.

• 

  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.

• 

  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.

• 

  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 10x 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.

• 

  IF Staining of HT-29 using 83653-5-RR (same clone as 83653-5-PBS)

  Immunofluorescent analysis of (4% PFA) fixed HT-29 cells using CEA antibody (83653-5-RR, Clone: 240666B12 ) at dilution of 1:250 and CoraLite®488-Conjugated AffiniPure Goat Anti-Rabbit IgG(H+L) (SA00013-2). This data was developed using the same antibody clone with 83653-5-PBS in a different storage buffer formulation.

• 

  Affinity and Kinetic Characterization of 83653-5-RR

  Biolayer interferometry (BLl) kinetic assays of 83653-5-RR against Human CEA were performed. The affinity constant is 0.734 nM.

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.
