Evaluating a new mixed-mode resin Diamond MMC Mustang using Capto MMC ImpRes as a benchmark

Diamond MMC Mustang is a relatively new mixed-mode resin, which mediates both cation exchange and hydrophobic interactions. In this work, we evaluated this resin using Cytiva's Capto MMC ImpRes, a well-established mixed-mode resin with similar properties, as a benchmark. The data suggest that in comparison with Capto MMC ImpRes, Diamond MMC Mustang exhibits comparable binding capacity and resolution. In addition, the resin under evaluation shows good lot-to-lot consistency. The information provided in this study allows users to have additional options when selecting mixed-mode resin for intermediate purification or final polishing, which is favourable especially at the present time when the supply chains of many manufacturers are negatively impacted by the coronavirus pandemic.
