Affinity purification of multifunctional oligomeric ligands synthesized via controlled radical polymerization

Abstract

Abiotic oligomeric ligands with a strong affinity for a target peptide sequence were isolated by affinity purification from a pool of 30-mer acrylic random ter-oligomers that were synthesized via a controlled radical polymerization process. Our results indicate that the oligomeric ligands with suitable sequence and/or stereochemical configurations for the target can be isolated from as-polymerized random co-polymers based on the affinity to the target. This process will be a powerful tool for the development of stable and inexpensive ligands that can be used to detect, neutralize and purify proteins with a target epitope sequence.
