Desalting and Buffer Exchange Market Trends, Growth, Share

WebAn anion exchange resin can be produced by charging the column with a negative ion, such as chloride or sulfate. Lauric acid's zwitterionic properties would cause it to elute first. Due to its negative charge, the dCMP would then begin to elute. Finally, the extremely polar hydroxyl group in D-galactose would cause it to elute. Desalting is used to remove salts from protein solutions, phenol or unincorporated nucleotides from nucleic acids or excess crosslinking or labeling reagents from conjugated proteins. Buffer exchange is used to transfer a protein solution into a buffer system appropriate for downstream applications such as ion exchange, electrophoresis or affinity chromatography. WebIon exchange chromatography (IEC) uses positively or negatively charged resins to bind proteins based on their net charges in a given buffer system (pH). Especially in commercial operations involving production of monoclonal antibodies, conditions for IEC can be determined that bind and release the target antibody with a high degree of specificity. fnath 17
