DNA-Encoded Macrocyclic Peptide Library.

DNA-encoded library technology (ELT) is a cutting-edge enabling technology platform for drug discovery. Here we describe how to design and synthesize a macrocyclic DNA-encoded library; how to perform selection, sequencing, and data analysis to identify potential active peptides; and how to synthesize off-DNA peptides to confirm activity. This approach provides an effective tool for pharmaceutical research based on peptides.
