Introduction to Hydrophobic Interaction Chromatography …

Mixed-mode chromatography (MMC), or multimodal chromatography, refers to chromatographic methods that utilize more than one form of interaction between the stationary phase and analytes in order to achieve their separation. What is distinct from conventional single-mode chromatography is that the secondary interactions in MMC cannot be too weak, and thus they also contribute to the retention of the solutes. WebSartorius Mixed-Mode (MM) chromatography ligands interact with target protein molecules through multiple types of interactions such as affinity, hydrophobic interaction (HIC), and cation/anion exchange. These multimodal separation mechanisms allow resins to be applied to solve challenging purification problems where traditional IEX, HIC, or ... ireland team vs italy
