A column is used that is filled with a charged stationary phase on a solid support, called an ion-exchange resin. The separation of proteins from the crude mixture obtained from the blood serum. Ion Exchange chromatography Principle The charged molecules in the sample are separated by the electrostatic forces of attraction when they pass through the ionic resin at particular pH and temperature. Working Principle of ion exchange chromatography. Ion exchange high-performance liquid chromatography is a scientific analysis technique that separates molecules based on their charge. Ion chromatography (IC) broadly refers to the separation of ions and includes three distinct mechanisms, namely, ion exchange, ion exclusion and ion pairing. If the buffer pH level is raised above the pI of a protein, it also carries a net negative charge. The major difference between affinity and ion-exchange chromatography is that affinity chromatography is used to separate charged or uncharged . The main classes of substances used are: modified organic polymer . A number of different chromatographic techniques are used for the purification and analysis of proteins. Anion exchange chromatography is a natural choice for separation of acidic glycans such as GAGs. Anion exchange chromatography is the separation technique for positively charged molecules by their interaction with negatively charged stationary phase in the form of ion-exchange resin. Step 5: The eluent displaces anion B, and anion B is eluted off the column. Using this method the inorganic ions can also be separated. It can use more commonly for both analytical and preparative purposes. Ion-exchange chromatography is a type of chromatography that separates analytes based on charge. Ion exchange chromatography (IEX) separates biomolecules according to differences in their net surface charge. Almost all charged molecules such as small amino acids, nucleotides and large proteins can separate using this method.
