Redefine and simplify your pharmaceutical manufacturing process. 3M’s anion exchange (AEX) chromatography, single-use, hybrid purifier is designed for bringing chromatography in upstream processing for particle control and reduction of DNA and host cell proteins.
3M™ Polisher ST is an anion exchange (AEX) chromatographic solution designed for the downstream processing of monoclonal antibodies (mAbs) and other recombinant proteins in flow-through mode. 3M Polisher ST is designed to reduce host cell protein impurities, viruses and other negatively charged contaminants in flow-through polishing chromatography of biopharmaceutical process streams.
3M Polisher ST is a synthetic, hybrid purifier containing two complementary AEX-functional media: a quaternary ammonium (“Q”) functional nonwoven and a guanidinium-functional membrane. The upstream Q-functional nonwoven provides reduction of turbidity (when present), DNA, and endotoxin, as well as a portion of the product’s AEX capacity for HCP and virus reduction. The downstream guanidinium functional membrane layers of 3M Polisher ST are salt tolerant and provide high HCP and virus reduction performance in a wider range of conditions compared to conventional Q-functional AEX resins.
Lab scale capsules are available now. Production capsules will be available at a later date.
3M™ Emphaze™ AEX Hybrid Purifier incorporates ion exchange chromatography and membrane filtration to provide chromatographic clarification and mechanical separation by size. At the heart of the hybrid solution is an anion exchange hydrogel media based on a non-woven material support that carries quaternary ammonium (Q) functionality. It works by using anion exchange chromatography in a single-use device.
The anion exchange chromatography of the functional nonwoven provides substantial reduction of soluble impurities and of insoluble particles below 0.1 microns for superior turbidity reduction. Users may see substantial reductions of DNA and host cell proteins (HCP). Integrating the purifier at the clarification stage may reduce the total cost of ownership for the monoclonal antibodies (mAb) purification process.
3M Polisher ST is a synthetic, fully encapsulated anion exchange product containing two complementary AEX-functional medias: a quaternary ammonium (“Q”) functional nonwoven and a guanidinium-functional membrane. The Q-functional nonwoven provides reduction of turbidity (when present), DNA and endotoxin, as well as a portion of the product’s AEX capacity for HCP and virus reduction. The guanidinium functional membrane provides salt tolerant HCP and viral clearance over a wider range of pHs compared to the Q chemistry.
3M Polisher ST eliminates the need for packing and cleaning validation and has 100X higher binding capacity for proteins, viruses, virus-like particles, and other large negatively charged complexes when to compared to resins.
From anion exchange chromatographic clarification of cell cultures, to bioburden reduction and flow through chromatography for polishing, 3M provides a range of technologies to deliver robust scalable solutions for applications in biotech.
Clarification tools designed for particle size control in clarified cell culture fluid. 3M offers efficient depth filters that enable high throughput. This can eliminate the need for centrifugation and enable implementation of a fully single-use clarification process train, completely scalable from lab to pilot to manufacturing.
3M Polisher ST is a compact, small footprint solution. It has a high capacity and can deliver greater purity and yield in the polishing step of the downstream process. 3M Polisher ST allows a facility strategy that can overcome scale limitations and enable cost-efficient manufacturing to support the growing demand for biologics. It can be deployed in a batch process or as part of a connected continuous downstream process for the flexible facility of the future. Find out more in the brochure below.

3M chromatography single use hybrid purifiers are designed for soluble and insoluble impurities reduction using anion exchange chromatography in clarification of mAbs and other recombinant proteins. Designed for DNA reduction, 3M™ Emphaze™ AEX Hybrid Purifier is a multi-mechanism single-use device containing anion exchange chromatography media integrated with a fine particle, bioburden reduction membrane.
The 3M Emphaze AEX Hybrid Purifier is a combination of two types of media (anion exchange chromatographic functional nonwoven and membrane) that work together to provide unsurpassed product purity when using a single unit operation. The integral combination of the 0.2 micron rated membrane and anion exchange nonwoven provides robust reduction of insoluble particles well below 0.1 micron.
