Advancements in polymer resins for solid-phase peptide synthesis
… attempting to fold a protein on resins with very high loading results in folding errors. In order to overcome these issues, we attempted to develop a novel core-shell polymer support, containing unprotected amine functional groups at low concentration on the resin surface and a large quantity of …
