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 ... WebMixed mode chromatography (or multimodal chromatography, MM) is a liquid chromatography technique used for the purification of proteins and other biomolecules. It can be successfully used in research, process development, and bioprocessing to purify …
WebThe chromatography model has been explained in detail before by Vetter et al. as a modified SMA model for Mixed-Mode based on the Steric Mass Action Isotherm of Nfor et al. , which considers the pH and salt concentration changes typical for mixed-mode chromatography (MMC) and the lumped pore diffusion model (LPD) . WebOct 13, 2024 · How Gas Chromatography Works First, a liquid sample is prepared. The sample is mixed with a solvent and is injected into the gas chromatograph.
