Design of Ligands for Affinity Purification of G-CSF Based on Peptide Ligands Derived from a Peptide Library

摘要

Combinatorial peptide libraries have become powerful tools to screen functional ligands by the principle of affinity selection. We screened in a phage peptide library to investigate potential peptide affinity ligands for the purification of human granulocyte colonystimulation factor(hGCSF). Peptide ligands will be promising to replace monoclonal antibodies as they have advantages of high stability, efficiency, selectivity and low price.
