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. …
