Long description
Ep-CAM is a 40 kD glycoprotein and can be detected at the basolateral membrane of the majority of epithelial tissues, where it is intriCately linked with the cadherin-Catenin complex and hence the fundamental WNT pathway responsible for intracellular signalling and polarity. This antigen functions as a homotypic calcium-independent cell adhesion molecule. Of particular interest, Ep-CAM appears to be overexpressed by the majority of Human epithelial carcinomas, including colorectal, breast, prostate, head and neck, and hepatic carcinomas. The antigen is being used as a target for immunotherapy of Human carcinomas. Formation of Ep-CAM-mediated adhesions has a negative regulatory effect on adhesions mediated by classic cadherins, which may have strong effects on the differentiation and growth of epithelial cells. Ep-CAM overexpression was suggested to be associated with enhanced epithelial prolifeRation.

Antibody s specificity
The G8.8 antibody reacts with CD326/Ep-CAM (Epithelial Cell Adhesion Molecule), also known as gp-40 in the Mouse. Ep-CAM is a 40-42-kDa cell-surface glycoprotein expressed on thymic epithelial cells, thymic dendritic cells, immature thymocytes, a small subset of peripheral T lymphocytes, intestinal epithelium, kidney-collecting tubule epithelium, Keratinocytes, Langerhans cells, as well as lymph node and splenic dendrititc cells.

-
Antibody s suited for
G8.8 is suitable for immunoblotting, immunoprecipitation, immunocytochemistry and immuno-histochemistry on frozen tissues and flow cytometry. Optimal antibody dilution should be determined by titration; recommended range is 1:25 – 1:200 for flow cytometry, and for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 – 1:1000 for immunoblotting applications.

Storage
Store at 4°C, or in small aliquots at -20°C.

About
Rats are used to make rat monoclonal anti mouse antibodies. There are less rat- than mouse clones however. Rats genes from rodents of the genus Rattus norvegicus are often studied in vivo as a model of human genes in Sprague-Dawley or Wistar rats.
