This monoclonal antibody is elicited against the salivary glycoprotein Human Extra Parotid Glycoprotein (EP-GP). This protein is identical to the gross cystic disease fluid protein GCDFP-15, secretory actin binding protein (SABP) and glycoprotein 17 (GP-17). In immunoblotting, the antibody reacts with its antigen in saliva, tear fluid, seminal plasma and sweat. It reacts in immunohisto logical sections of submandibular tissues. GCDFP-15 is expressed by breast carcinomas (primary and metastatic lesions) with apocrine features.
