Phage display random heptapeptide library was screened with recombinant P37 in this study. The positive phage clones were identified by ELISA and were sequenced, and the amino acid sequences of the polypeptides displayed on phage were deduced. After GST-polypeptides fusion protein was constructed and expressed, its binding to P37 was determined by GST-pull down and Western blot. After 4 rounds of bio-panning, the enriched positive phage clones were identified by ELISA. Eighteen positive phage clones were sequenced and the peptide sequences were as follows. ACAPKPPWLC (12/18), RPLSIDPWSPHL (3/18), RPLSNDPWSPHL (1/18), QNMMSPIEGVRI (1/ 18) and WAPEKDYMQLMK (1/18). The results from GST-pull down and Western blot showed that peptide RPLSIDPWSPHL could interact with P37. The study will be helpful for identifying the protein reacting with P37.
