Background

Epithelial Cellular Adhesion Molecule (EpCAM), also known as KS1/4, gp40, GA733-2, 17-1A, and TROP-1, is a 40 kDa transmembrane glycoprotein composed of a 242 amino acid (aa) extracellular domain with two epidermal-growth-factor-like (EGF-like) repeats within the cysteine-rich N-terminal region, a 23 aa transmembrane domain, and a 26 aa cytoplasmic domain. Human and mouse EpCAM share 82% aa sequence identity. In human, EpCAM also shares 49% aa sequence homology with TROP-2/EGP-1. During embryonic development, EpCAM is detected in fetal lung, kidney, liver, pancreas, skin, and germ cells. In adults, human EpCAM is detected in basolateral cell membranes of all simple, pseudo-stratified, and transitional epithelia, but is not detected in normal squamous stratified epithelia, mesenchymal tissue, muscular tissue, neuro-endocrine tissue, or lymphoid tissue (1). EpCAM expression has been found to increase in actively proliferating epithelia tissues and during adult liver regeneration (1, 2). EpCAM expression is also found to increase in human malignant neoplasias, with most carcinoma expressing EpCAM including those of arising from squamousal epithelia (1). EpCAM has been shown function as a homophilic Ca²⁺ independent adhesion molecule (3). Homophilic adhesion via EpCAM requires the interaction of both EGF-like repeats, with the first EGF-like repeat mediating reciprocal interaction between EpCAM molecules on opposing cells, while the second repeat is involved in lateral interaction of EpCAM. Lateral interaction of EpCAM lead to the formation of dimers and tetramers (4). During homophilic adhesion the cytoplasmic tail of EpCAM interacts with the actin cytoskeleton via a direct association alpha -actinin (5).

FAQs for EpCAM/TROP1 Antibody (FAB9601A). (Showing 1 - 1 of 1 FAQs).

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.
