Phage peptide libraries are collections of the specific length of short peptides,and they are based on phages as their carriers.They include mimotope libraries and peptide antibody libraries.Phage-displayed peptide libraries have been used to isolate specific ligands for numerous protein targets,and they have been proven useful in defining antigen momitopes,rapid determination of binding energetics at protein-protein interfaces,designing of vaccine and tumor research aspects.This review summarized the research progression of phage peptide library.
