Description | The antibody HEA125 is directed against human EpCAM. Ep-CAM is a 34 kD glycoprotein and can be detected at the basolateral membrane of the majority of epithelial tissues. It is intricately linked with the cadherin-catenin complex and hence the fundamental WNT pathway responsible for intracellular signalling and polarity. Ep-CAM functions as a homotypic calcium-independent cell adhesion molecule. Of particular interest, Ep-CAM appears to be overexpressed at the cell surface of the majority of human epithelial carcinomas, including colorectal, breast, prostate, head and neck, and hepatic carcinomas. The antigen is therefore being used as a target for immunotherapy of human carcinomas. Also, Ep-CAM monoclonal antibodies are now extensively use |
