Phage display peptide library construction

Phage display peptide library construction for high-affinity ligand selection enables researchers to screen billions of peptide variants for specific binding properties. Using M13 phage formats, both linear and Cys-constrained libraries are built to identify peptides with strong target affinity. This technique supports applications in drug discovery, diagnostics, and protein interaction studies. Proper sequencing and screening strategies ensure reliable results, with lyophilized peptides delivered ready for experimental use.
