Bind and elute vs flow through mode

WebThe trend appeared to initially be to utilize CEX in a bind and elute mode as the first polishing step followed by AEX in a flow-through mode of operation. mAbs usually have a basic pI and hence bind tightly to CEX resins and tend to flow-through readily on AEX resins. The CEX step clears both HMW and HCP. WebMar 1, 2024 · Membrane based ion-exchange (IEX) and hydrophobic interaction chromatography (HIC) for protein purification is often used to remove impurities and aggregates operated under the flow-through mode. IEX and HIC are also limited by capacity and recovery when operated under bind-and-elute mode for the fractionation …
