Identifies a high molecular weight glycoprotein (MUC1) expressed on the apical surface of many glandular epithelia, including those of the gastrointestinal, respiratory, urinary, and reproductive tracts. In tumors, MUC1 expression is increased and more diffuse, aiding in the evaluation of breast, colon, lung, gastric, and pancreatic cancers.
