The peptide EPPT (Glu-Pro-Pro-Thr)(SEQ I YD NO: 1) selectively binds a mucin expressed by epithelial tumors. It may be incorporated into larger molecules, such as, peptides consisting of the sequence EPPT and further amino acids to form a peptide of up to 30 amino acids, and may be radiolabelled or used to guide toxins, etc. to cells expressing the mucin. |
