EPCAM and familial pancreatic carcinoma: Interestingly, a comparison of the use of two antibodies (clones: MOC-31 and 9-2, recognizing the N- and C-terminus domains of EpCAM, respectively) has been carried out recently on human pancreatic cancer (34) and on a comprehensive multitissue microarray (35) to allow discrimination between two variants of the membranous EpCAM form: EpEx+/EpICD+ (EpCAMMF) and EpEx+/EpICD− (EpCAMMT).
