MUC1 Antibody / Mucin-1

This antibody recognizes proteins in MW range of 265-400 kDa, identified as different glycoforms of MUC1 (Mucin-1) or EMA (epithelial membrane antigen). The alpha subunit has cell adhesive properties. It can act both as an adhesion and an anti-adhesion protein. MUC1 / Mucin-1 may provide a protective layer on epithelial cells against bacterial and enzyme attack. The beta subunit contains a C-terminal domain, which is involved in cell signaling through phosphorylations and protein-protein interactions. In immunohistochemical assays, the MUC1 / EMA antibody superbly stains routine formalin/paraffin carcinoma tissues. MUC1 antibody is useful as a pan-epithelial marker for detecting early metastatic loci of carcinoma in bone marrow or liver.
