Abstract
CM resin is a totally PEG-based resin, made exclusively from primary ether bonds and therefore highly chemically stable. Compared to other PEG resins, it exhibits good loading and is user friendly because of its free-flowing form upon drying. It shows improved performance over PS resins for the preparation of hydrophobic, highly structured poly-Arg peptides. In combination with ψPros, it allows the synthesis of small proteins such as the chemokine RANTES. Like other PEG-based resins, CM resin swells well in biocompatible solvents such as water, thereby allowing on-bead screening. Furthermore, the high loading of this resin permits the use of a tiny quarter of a bead as a microreactor for HPLC and MALDI-TOF analysis, thus further extending its applications in the field of combinatorial chemistry.
