Specificity & Comments

Beta-catenin associates with the cytoplasmic portion of E-cadherin, which is necessary for the function of E-cadherin as an adhesion molecule. In normal tissues, beta-catenin is localized to the membrane of epithelial cells, consistent with its role in the cell adhesion complex. In breast ductal neoplasia, beta-catenin is usually localized in cellular membranes. However, in lobular neoplasia, a marked redistribution of beta-catenin throughout the cytoplasm results in a diffuse cytoplasmic pattern. Immuno-staining of beta-catenin and E-cadherin is helps in the accurate identification of ductal and lobular neoplasms, including a distinction between low-grade ductal carcinoma in situ (DCIS) and lobular carcinoma. Additionally, some rectal and gastric adenocarcinomas demonstrate diffuse cytoplasmic beta-catenin staining and a lack of membranous staining, mimicking the staining pattern observed with lobular breast carcinomas.

Known Applications & Suggested Dilutions

Flow Cytometry (0.5-1ug/million cells)
Immunofluorescence (1-2ug/ml)
Western Blotting (0.5-1ug/ml)
Immunohistology (Formalin-fixed) (1-2ug/ml for 30 minutes at RT)
(Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Tis with1mM EDTA, pH 9.0, for 10-20 min followed by cooling at RT for 20 minutes)
Optimal dilution for a specific application should be determined.

Positive Control

HeLa or MCF-7 cells. Breast carcinoma
