|Target/Specificity||A synthetic peptide corresponding to residues in C-terminus (cytoplasmic domain) of human Ep-CAM was used as immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Epcam Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||GA733-2, M1S2, M4S1, MIC18, TACSTD1, TRO|
|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.|
|Cellular Location||Lateral cell membrane; Single-pass type I membrane protein. Cell junction, tight junction. Note=Colocalizes with CLDN7 at the lateral cell membrane and tight junction|
|Tissue Location||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.|

Epithelial cell adhesion molecule (Ep-CAM) is a monomeric membrane glycoprotein that is expressed on virtually all epithelial cell membranes and on a variety of epithelial carcinomas (1-3). Ep-CAM is overexpressed in a variety of human carcinomas and is, therefore, a potential therapeutic target for human solid tumors (4). Ep-CAM contains an extracellular domain with two epidermal growth factor-like repeats, followed by a cysteine-poor region, which are necessary for the adhesion properties of the molecule (5).
