WebOct 1, 2024 · Weak partitioning mode is different from flow-through mode. In comparison to binding under flow-through mode, increased amount of product binds to the resin under weak partitioning mode [7]. Thus, under this mode the binding of impurities that originally bind stronger than the product is further enhanced, which allows more complete removal … Webmonomeric counterparts. Both bind-elute and flow-through mode HIC applications have been successfully used to remove mAb aggregates in commercial processes. In the following example, a highly efficient flow-through process for mAb aggregate removal was developed. Using POROS Benzyl Ultra, high-throughput screening (HTS) was performed to

WebProteins bound to ion exchange resins are bound via non-covalent ionic (salt-bridge) interactions. We can compete for these ionic binding sites on the resin with other ionic … WebIn multimodal chromatography, the choice between bind/elute and flowthrough mode is more complex than when using a single method, such as IEX, because multiple types of interactions are occurring in multimodal chromatography, and the strength of these individual interactions often depends on the overall process conditions.
