Background

Epithelial Cellular Adhesion Molecule (EpCAM), also known as ECD326 and TROP-1 is a 36-41 kDa member of the TROP family of meolcules (1, 2). It is a type I transmembrane glycoprotein that is found on embryonic stem cells and adult non-squamous epithelium such as (respiratory) psuedostratified, (mammary) cuboid, and (colon) simple columnar epithelium. In mouse, the molecule has also been reported on T cells, Langerhans cells and thymic epithelium. Mature mouse EpCAM is 292 amino acids (aa) in length. It possesses a 243 aa extracellular region that contains one thyroglobulin type I domain. Such domains are associated with cathepsin binding and inhibition (2). On the cell surface, EpCAM is reported to participate in TEM (Tetraspanin-enriched microdomain) formation in concert with CD44v6, CD9, ADAM10, Claudin-7 and TS8. It is also noted to form homodimers in-cis and homotetramers in-trans. Although this would suggest the EpCAM acts as an adhesion molecule, in effect it does not, instead acting as a disruptor of the E-Cadherin:cytoskeleton interaction, and thus promoting cell migration (1, 2). The extracellular domain (ECD) of EpCAM undergoes multiple cleavages, principally between Ser200 and Ala210 (3). Cleavage at the Arg80-Arg81 site does not generate a soluble fragment, but rather a disulfide-linked "heterodimer" (3). Cleavage after Gly264 in the juxtamembrane region is followed by secretase cleavage of the transmembrane fragment, generating an ICD that translocates to the nucleus (4). The ECD of mouse EpCAM shares 81% and 90% aa sequence identity with human and rat EpCAM, respectively.

FAQs for EpCAM/TROP1 Antibody (FAB8998R). (Showing 1 - 1 of 1 FAQ).

1. I'm looking for EpCAM antibody for rat. Do you have any antibody which can use FACS?
   • We unfortunately do not have any EpCAM antibodies validated in FACS for detection of the rat protein. I am sorry for any inconvenience. I do have three products to EpCAM that can detect the rat protein. These products have been validated to detect the native rat protein, so they may work for FACS however they have not yet been tested in that particular application. If you would like to try them in your experiment you would qualify for our Innovator's Reward Program. This program was designed to help scientists with the cost of their antibodies in return for valuable information. If you decide to test an antibody in a previously untested species or application we will issue you a credit for the purchase price of the antibody in exchange for a review of your experiment using our product.
