MiMode™ PuraBead® HX1

Product overview

 MiMode™ PuraBead® HX1 is a mixed-mode chromatography resin designed to provide a versatile and cost-effective solution for biomolecule purification. Built on the robust PuraBead® 6HF base matrix, it combines aromatic hydrophobic and hydrogen-bonding interactions, enabling both bind-and-elute and flow-through polishing applications.

Unlike single-mode affinity solutions, MiMode™ PuraBead® HX1 offers broad selectivity, making it suitable as a platform technology across multiple molecule classes. The synthetic ligand ensures strong base stability, while the PuraBead® 6HF matrix delivers excellent flow properties and scalability from discovery through to large-scale manufacturing.

With a wide operational pH range, compatibility with common buffer systems, and straightforward cleaning using sodium hydroxide, MiMode™ PuraBead® HX1 integrates seamlessly into existing workflows. It is available in high-throughput screening formats as well as process-scale volumes, supporting both rapid development studies and commercial production needs.
