- Background
- Epithelial cell adhesion molecule (EpCAM) is a transmembrane glycoprotein mediating Ca2+-independent homotypic cell–cell adhesion in epithelia. This gene encodes a carcinoma-associated antigen and is a member of a family that includes at least two type I membrane proteins. This antigen is expressed on most normal epithelial cells and gastrointestinal carcinomas and functions as a homotypic calcium-independent cell adhesion molecule. The antigen is being used as a target for immunotherapy treatment of human carcinomas. Mutations in this gene result in congenital tufting enteropathy.

- Immunogen
- A synthetic peptide corresponding to a sequence in the middle region of human EPCAM, different from the related mouse sequence by fifteen amino acids, and from the related rat sequence by sixteen amino acids.
- Clonality
- Polyclonal
- 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. .

- Form
- Lyophilized
- Reconstitution
- Add 0.2ml of distilled water will yield a concentration of 500ug/ml.
- 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. .
