Methods: MUC1/Y extracellular domain was used as a target molecule to biopan Ph. D. 12 phage randem peptide library. Two protocols using affinity gel and cell culture plates respectively were carried out. Positive phage clones were identified by ELISA. ssDNA sequencing was done on 16 positive phage clones to get the amino acid sequences of MUC1/Y-binding peptides. Immunohistochemistry was done to show the capacity and specificity of positive phage clones to bind the tumor cell lines.
