Size-Exclusion Chromatography: A Twenty-First Century Perspective
Introduction. As is, perhaps, the case with many of its users, size-exclusion chromatography (SEC), born in the 1950s, has gone from being the "hot, young, new thing" in the 1960s and early-70s, to irresponsible youth in the late-70s and 1980s (when at-best-dubious calibrant-relative results ran rampant through the literature), to questioning adult in the 1990s (when the combined ...
Size-Exclusion Chromatography as a Technique for the Investigation of
Size-exclusion chromatography (SEC) is an increasingly popular technique, which has been rediscovered for the purposes of extracellular vesicle (EV) isolation and purification from diverse biofluids. A systematic review was undertaken to identify all papers that described size exclusion as their primary EV isolation method in cancer research.
Size-Exclusion Chromatography for the Analysis of Protein
For these largely protein-based therapies, the quantitation of aggregates is of particular concern given their potential effect on efficacy and immunogenicity. This need has renewed interest in size-exclusion chromatography (SEC). In the following review we will outline the history and background of SEC for the analysis of proteins.
Size-Exclusion Chromatography: A Twenty-First Century Perspective
Abstract. Now in its sixth decade, size-exclusion chromatography (SEC) remains the premier method by which to determine the molar mass averages and distributions of natural and synthetic macromolecules. Aided by its coupling to a variety and multiplicity of detectors, it has also shown its ability to characterize a host of other physicochemical ...

Abstract. Size exclusion chromatography (SEC) is a historical technique widely employed for the detailed characterization of therapeutic proteins and can be considered as a reference and powerful technique for the qualitative and quantitative evaluation of aggregates. The main advantage of this approach is the mild mobile phase conditions that ...
Size exclusion chromatography for the characterization and quality
Size exclusion chromatography (SEC) is a powerful tool for analyzing size variants of proteins in academic and biopharmaceutical laboratories. Recent advancements in SEC methodology have improved size separation range, resolution, and sensitivity for analytes of interest.

SEC is one of the most widely used sized-based separation techniques, which separates species based on their hydrodynamic radius. The SEC principle of operation is quite simple, and is illustrated in Fig. 1.As the sample flows through the column, molecules could be either totally excluded from the pores of the stationary phase (if they are sufficiently large), they could fully penetrate into ...
Size exclusion chromatography (SEC)
Size exclusion chromatography (SEC) is a liquid phase chromatographic technique for separating molecules, proteins, macromolecules, and nanoparticles (below 100 nm) solely according to their hydrodynamic volume in solution.Classification depends on the size- and shape-dependent exclusion of components in the pores of the stationary phase material, that is, larger and less mobile components ...

A Review Size-exclusion Chromatography for The Analysis of Protein
HISTORY. The concept of size-based separations by chromatography was first speculated by Synge and Tiselius, [Citation 21] based on the observation that small molecules could be excluded from the small pores of zeolites as a function of their molecular size. [Citation 22] The term "molecular sieve," coined by J. W. McBain [Citation 23] to describe this property of zeolites, was ...

Size-Exclusion Chromatography
Abstract. Size-exclusion chromatography (also known as gel filtration chromatography) is a technique for separating proteins and other biological macromolecules on the basis of molecular size. Originally developed in the 1950s, the technique was developed using crosslinked dextran ( 1, 2 ).
