MiMode PuraBead® mixed-mode resins Smart selectivity for complex purification challenges
The MiMode PuraBead® range introduces a new generation of mixed-mode chromatography resins, engineered to deliver powerful selectivity where conventional methods fall short. By combining multiple binding interactions, MiMode® resins provide advanced separation capability for proteins, viral vectors, nucleic acids, and other challenging biomolecules.
Choose from three distinct resin families designed to support a wide range of applications.
Hydrophobic mixed-mode resins: MiMode PuraBead® HX1, HX2, HL3, HL4 Harness hydrophobic and hydrogen-bonding interactions to capture tricky proteins, aggregates, and viral particles with confidence.
Anion-exchange mixed-mode resins: MiMode PuraBead® AX1 Combines anionic and hydrophobic interactions for improved nucleic acid clearance and viral purification.
MiMode® resins are available in multiple formats to support every stage of development. The MiMode® range ensures seamless scalability, with formats spanning high-throughput 96-well plates for rapid resin screening, RoboColumns® and pre-packed SNAP® columns for method development, and Evolve® and Evolve®D columns for GMP-ready processes. Each resin is manufactured under ISO 9001 quality standards, delivering consistent performance and robust reproducibility. With MiMode®, developers can simplify workflows, reduce purifications steps, and improve impurity clearance while maintaining high recovery. The MiMode® range brings mixedmode power to your toughest separations—flexible tools, smarter workflows, better results.
Cation-exchange mixed-mode resins: MiMode PuraBead® CX1, CX2, CBX1, CBX2 Integrating cation exchange, hydrophobic, and hydrogenbonding interaction contributions to deliver strong capture and polishing performance for positively charged proteins such as monoclonal antibodies and enzymes. The MiMode PuraBead® CXB1 and CBX2 resins also have contributory boronate ester interactions to provide additional selectivity for complex feed streams such as glycosylated biomolecules.
