General description

Episialin (mucin-1) is an epithelial transmembrane oncoprotein that occurs in glandular tissues. This oncoprotein mediates ErbB1 receptor transport and subsequently regulates cell survival. Episialin also modulates p53-responsive genes under conditions of genotoxic stress and also co-activates the transcription of Wnt target genes. Overexpression of Episialin has been associated with most human cancers
Monoclonal Anti-Episialin (EMA) antibody is specific for the repetitive protein epitope on the episialin long extracellular domain. This epitope is relatively insensitive to glycosylation. The antibody stains 2 bands (ranging between 265-400 kD) by immunoblotting. The product also reacts with highly glycosylated episialin in epithelial cell tumors and large cell anaplastic lymphomas. In immunohistological assays, enzymatic pre-treatment of formalin-fixed, paraffin-embedded sections may enhance the staining intensity.


Monoclonal Anti-Episialin (EMA) antibody is suitable for use in immunohistochemistry (1:200 using formalin-fixed, paraffin-embedded sections of human breast carcinoma), immunoprecipitation and microarray.
