Gel filtration on soft gels has been employed for over 40 years for the separation, desalting and molecular weight estimation of peptides and proteins. Technical improvements have given rise to high-performance size-exclusion chromatography (HPSEC) on rigid supports, giving more rapid run times and increased resolution. Initially, these packings were more suitable for the separation of proteins than of peptides, but supports that operate in the fractionation range < 10,000 Daltons (Da) are now available. In this report, HPSEC is described in relation to its application to peptides, especially regarding purification, estimation of molecular weight and study of molecular associations.
