Solid-phase peptide synthesis: a silver anniversary report.

Abstract

It has been a quarter of a century since Merrifield's initial report on solid-phase peptide synthesis. The field has matured significantly in recent years with a better understanding of the underlying chemistry. This is reflected by new, milder orthogonal protection schemes and more efficient coupling methods, some of which have been incorporated into automated systems. Advances in purification, especially high performance liquid chromatography, have had a major impact. The efficacy of these improvements has been demonstrated by an impressive litany of applications to biological problems.
