  • Description

    Mouse monoclonal [Ber-EP4] to EpCAM
  • Host species

  • Specificity

    Epithelial specific antigen is cell surface glycoprotein and is broadly distributed in epithelial cells and displays a highly conserved expression in carcinomas. Epithelial specific antigen has been know to play an important role as tumor-cell marker in lymph nodes from patients with esophageal carcinoma. Epithelial specific antigen can be used to distinguish between basal cell and basosquamous carcinomas and squamous cell carcinoma of the skin.

  • Function

    May act as a physical homophilic interaction molecule between intestinal epithelial cells (IECs) and intraepithelial lymphocytes (IELs) at the mucosal epithelium for providing immunological barrier as a first line of defense against mucosal infection. Plays a role in embryonic stem cells proliferation and differentiation. Up-regulates the expression of FABP5, MYC and cyclins A and E.
  • Tissue specificity

    Highly and selectively expressed by undifferentiated rather than differentiated embryonic stem cells (ESC). Levels rapidly diminish as soon as ESC's differentiate (at protein levels). Expressed in almost all epithelial cell membranes but not on mesodermal or neural cell membranes. Found on the surface of adenocarcinoma.
  • Involvement in disease

    Defects in EPCAM are the cause of diarrhea type 5 (DIAR5) [MIM:613217]. It is an intractable diarrhea of infancy characterized by villous atrophy and absence of inflammation, with intestinal epithelial cell dysplasia manifesting as focal epithelial tufts in the duodenum and jejunum.
    Defects in EPCAM are a cause of hereditary non-polyposis colorectal cancer type 8 (HNPCC8) [MIM:613244]. HNPCC is a disease associated with marked increase in cancer susceptibility. It is characterized by a familial predisposition to early-onset colorectal carcinoma (CRC) and extra-colonic tumors of the gastrointestinal, urological and female reproductive tracts. HNPCC is reported to be the most common form of inherited colorectal cancer in the Western world. Clinically, HNPCC is often divided into two subgroups. Type I is characterized by hereditary predisposition to colorectal cancer, a young age of onset, and carcinoma observed in the proximal colon. Type II is characterized by increased risk for cancers in certain tissues such as the uterus, ovary, breast, stomach, small intestine, skin, and larynx in addition to the colon. Diagnosis of classical HNPCC is based on the Amsterdam criteria: 3 or more relatives affected by colorectal cancer, one a first degree relative of the other two; 2 or more generation affected; 1 or more colorectal cancers presenting before 50 years of age; exclusion of hereditary polyposis syndromes. The term 'suspected HNPCC' or 'incomplete HNPCC' can be used to describe families who do not or only partially fulfill the Amsterdam criteria, but in whom a genetic basis for colon cancer is strongly suspected. Note=HNPCC8 results from heterozygous deletion of 3-prime exons of EPCAM and intergenic regions directly upstream of MSH2, resulting in transcriptional read-through and epigenetic silencing of MSH2 in tissues expressing EPCAM.
  • Sequence similarities

    Belongs to the EPCAM family.
    Contains 1 thyroglobulin type-1 domain.
  • Post-translational

    Hyperglycosylated in carcinoma tissue as compared with autologous normal epithelia. Glycosylation at Asn-198 is crucial for protein stability.
  • Cellular localization

    Lateral cell membrane. Cell junction > tight junction. Co-localizes with CLDN7 at the lateral cell membrane and tight junction.

Thank you for your inquiry.

For ab758, the immunogen that was used was cytoskeletal extract of human hepatocellular carcinoma cell line, Hep3B. We have not validated this antibody in pig. But the human sequence is 85% homologous with the pig cytokeratin 8 sequence. We generally say anything with >85% homology would be expected to cross-react, so this is right on the edge. However, we do have two anti-cytokeratin 8 antibodies that we know do work in pig as ab2531 and ab2530.



For ab27988, this antibody has been validated in pig and we therefore guarantee it will work for pig in IHC-P, IHC-Fr in accordance with our Abpromise.

For ab7504, the immunogen was human breast carcinoma cell line, MCF-7. Pig and human EpCAM is 83% homologous, so this is a little low. We have an anti-EpCAM that is predicted (>90% homology) to cross-react with pig, and that is ab71916. However, this hasn't been validated and therefore not guaranteed in pig.


I have to check with the lab on ab32362 and ab124687 since I don't have the immunogens readily available to BLAST.

For ab28028, full length native protein (purified): Vimentin isolated from bovine eye lens was used as an immunogen. Pig vimentin and bovine vimentin are 97% homologous, so there is a good chance this will cross-react with pig. However this hasn't been tested and therefore isn't validated in pig. We do have a few vimentin antibodies that work in pig though,like ab20346 and ab8069.



For ab11333, cultured human thymic fibroblasts was used as an immunogen. We don't have a particular protein sequence to look up for this one, so unfortunately we don't know how/if it will work with pig.

I hope this information helps. I'll be in touch again once I hear about ab32362 and ab124687.

Thank you for contacting us. As shown on the datasheet of the anti-EpCAM ab71916, www.abcam.com/ab71916, SW480 whole cell lysate is a recommended positive control. As explained on the phone, to our knowledge ab7504 has been tested in Western Blot. This monoclonal may work in this application and some optimisation may be needed. Since this antibody works in IHC, it may recognise an epitope made up of non-contiguous amino acids in their native conformation. Although the amino acids of the epitope are separated from one another in the primary sequence, they can be closer to each other in the three dimensional structure of the protein. If this hypothesis is correct, the antibody will only recognize the epitope as it exists on the surface of the folded structure. It is imperative in these circumstances to run a western blot in non-denaturing conditions, and this will be noted on the datasheet in the applications section. In general, a non-denaturing condition simply means leaving SDS out of the sample and migration buffers and not heating the samples. Certain antibodies only recognize protein in its non-reduced form i.e. in an oxidized form (particularly on cysteine residues) and the reducing agents β-mercaptoethanol and DTT must be left out of the loading buffer and migration buffer (non reducing conditions). We recommend to perform a western blot using a buffer without ionic detergents (e.g. SDS) and ideally without non-ionic detergents (e.g. Triton X-100). Cell lysis with detergent-free buffer can be achieved by mechanical shearing, often with a Dounce homogenizer or by passing cells through a syringe tip. In these cases a simple Tris buffer will suffice. Do not heat the samples. For more details I would suggest to look at the protocols book : www.abcam.com/protocolsbook or the Western Blot guide https://www.abcam.com/ps/pdf/protocols/WB-beginner.pdf . I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for contacting us in regards to Anti-EpCAM antibody [Ber-EP4] (ab7504) and Anti-EpCAM antibody [HEA125] (ab46714). As discussed over the phone yesterday, we do not currently have any information regarding these antibodies having been used in Western blotting but I have seen information relating to antibodies produced from these clones having been used for this application. It therefore seems likely that they should be able to be used for this application. If you would like we could take a look at the protocol you have been using to perform Western blotting in order to see if there are any suggestions we can make to improve the likelihood of seeing the desired band. I have attached a questionnaire to this email for this purpose. However, the Invitrogen Dynabeads you have purchased work like immunoprecipitation and it may be that the antibodies from these clones are more appropriate to bind to the native epitope of the protein, not the denatured form detected in the Western blot. I hope this information has been of help.

Thank you for contacting us. THE A431, HCT116 and MCF etc express this target so lysates of these can be used as positive control. For more information about the tissue that expresses this target please check Human Protein Atlas. As discussed; SW480 cell line can also be used as positive control. However we do not have tested results of this cell line which we can forward you for comparison. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
