PNA Encoding (PNA=peptide nucleic acid): From Solution-Based Libraries to Organized Microarrays

Abstract Microarray-based technologies have attracted attention in chemical biology by virtue of their miniaturized format, which is well suited to probe ligand–protein interactions or investigate enzymatic activity in complex biological mixtures. A number of research groups have reported the preparation of surfaces on microarrays with specific functional groups to chemoselectively attach small molecules from libraries. We have developed an alternative method whereby libraries are encoded with peptide nucleic acid (PNA), such that libraries which exist as mixtures in solution self-assemble into an organized microarray through hybridization to produce readily available DNA arrays. This allows libraries synthesized by split and mix methods to be decoded in a single step. An asset of this method compared to direct spotting is that libraries can be used in solution for bioassays prior to self-assembly into the microarray format.
