Sec methode

WebSize exclusion chromatography (SEC) is a routine method for the characterization of biopharmaceuticals. The conventional SEC setup uses UV detection, due to high salt concentrations in commonly used buffers. In this study, the separation of proteins by denaturing SEC with direct coupling to a mass spectrometer (MS) was investigated. Web1 Oct 2024 · SEC is the standard method for protein aggregate analysis. The technique involves passing molecules through a column containing porous polymer or silica beads. …

Size-exclusion chromatography (SEC), also known as molecular sieve chromatography, is a chromatographic method in which molecules in solution are separated by their size, and in some cases molecular weight. It is usually applied to large molecules or macromolecular complexes such as proteins … See more The main application of size-exclusion chromatography is the fractionation of proteins and other water-soluble polymers, while gel permeation chromatography is used to analyze the molecular weight distribution of … See more The technique was invented in 1955 by Grant Henry Lathe and Colin R Ruthven, working at Queen Charlotte's Hospital, London. They later received the John Scott Award for this invention. While Lathe and Ruthven used starch gels as the matrix, Jerker Porath and … See more In real-life situations, particles in solution do not have a fixed size, resulting in the probability that a particle that would otherwise be hampered by a pore passing right by it. Also, the … See more Biochemical applications In general, SEC is considered a low-resolution chromatography as it does not discern similar … See more The advantages of this method include good separation of large molecules from the small molecules with a minimal volume of eluate, and that various solutions can be applied without interfering with the filtration process, all while preserving the … See more SEC is used primarily for the analysis of large molecules such as proteins or polymers.
