We demonstrate that a peptoid composed of five monomers and attached via a maleimide linker to a carrier protein elicits anti-peptoid, anti-linker and anti-carrier antibodies in rabbits. Specific anti-peptoid antibodies were affinity purified and used to reproducibly retrieve three specific peptoid-coupled beads from 20,000 irrelevant peptoid-beads using magnetic screening.
