Abstract:
AIM: To isolate peptides targeted binding and internalizing into glioblastoma cell line SWO-38. METHODS: Tumor cells were screened five rounds of whole cell screen through the Ph.D.-12 phage display library. The monoclone specific binding efficiency to the tumor cell was analyzed, and the DNA of phages were extracted, sequenced and translated to the sequences of amino acid. RESULTS: In the phage library after five rounds of screen , 10 of 13 monoclones had highly selective binding to SWO-38 cells. We found two repeated peptide sequences. CONCLUSION: Whole cell screening against tumor cells through random phage peptide library can obtain phage peptides with highly specific binding and internalizing ability. The peptides could be used as a therapy vector for tumor targeted delivery.
