Ion- exchange chromatography
Web15 okt. 2024 · Ion-exchange chromatography (IEX) separates proteins (or any biomolecules) based on differences in their net charge at a particular pH. Protein charge depends on the number and type of ionizable amino acid side chain groups. Each protein has an isoelectric point (pI), the pH at which the overall number of negative and positive … WebIon exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net ...
