Description: EpCAM (Epithelial cell adhesion molecule, CD326, KSA, TROP1) is a 40 kD cell-surface adhesion molecule participating in homophilic, calcium-independent cell-cell interactions. EpCAM is a type-I transmembrane protein, and is expressed primarily on the basolateral surface of most epithelia. Although normal epithelia express low levels of EpCAM, increased expression has been correlated with increased proliferation and progression to a mesenchymal phenotype. EpCAM has also been used as a diagnostic marker on circulating metastatic carcinoma cells, while cancer cells of non-epithelial origin do not express EpCAM.
Applications Reported: This 1B7 antibody has been reported for use in flow cytometric analysis, and immunohistochemical staining of frozen tissue sections.
Applications Tested: This 1B7 antibody has been tested by flow cytometric analysis of the A549 cell line. This can be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. This 1B7 antibody has been tested by immunohistochemistry of frozen tissue and can be used at less than or equal to 10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Filtration: 0.2 µm post-manufacturing filtered.
Ep-CAM is a ~40 kD glycoprotein, which functions as an epithelial cell adhesion molecule. Ep-CAM mediates Ca2+-independent homotypic interactions. 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. Ep-CAM is expressed in the majority of human carcinomas and is a marker for tumors of epithelial lineage.
