Size exclusion chromatography, or SEC, is a technique for separating proteins and other complex biomolecules in their native forms by size using aqueous eluents. For molecules of specific molecular weight, SEC can use used to detect and quantitate aggregates, fragments, monomers and dimer. This guide provides a comprehensive application overview for Biozen dSEC-2 Size Exclusion Columns.
