Immunogen
Purified recombinant EpCAM protein fragments expressed in E.coli.
Specificity
This antibody detects endogenous levels of EpCAM and does not cross-react with related proteins.
Formulation
Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.
Purification process (Immunogen)
The antibody was affinity-purified from mouse ascites by affinity-chromatography using epitope-specific immunogen.
Background
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. [provided by RefSeq, Dec 2008],

Cellular localization
Lateral cell membrane ; Single-pass type I membrane protein . Cell junction, tight junction . Colocalizes with CLDN7 at the lateral cell membrane and tight junction. .
Tissue expression
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.
