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 magnetic beads connect to epithelial-enrich. Only a small amount of the peptide is required to establish over 80% connectivity to ovarian cancer comparing to low connectivities to other cancer, showing high specificity for ovarian cancer. Thus the peptide of the present invention can be effective in early detection of ovarian cancer.
