Abstract
The present invention provides a novel peptide with high specificity for recognition of ovarian cancer. The peptide is selected using M13 phage display library and epithelial-enrich-conjugated magnetic beads. Only a small amount of the peptide is required to establish over 80% binding activity to ovarian cancer comparing to low binding activities to other cancers, showing high specificity for ovarian cancer. Thus the peptide of the present invention can be effective in early detection of ovarian cancer.
