- All-synthetic, highly functionalized media (contains no naturally-derived materials)
- Asymmetric membrane terminating with 0.2 µm bioburden reduction zone
- Excellent mAb recovery often equal to or greater than 95%
- Substantial turbidity, DNA, HCP and bioburden reduction
- Reduced surface area requirement of the downstream sterilizing grade membrane
- May offer differentiated protection of the protein A column for enhanced contaminant clearance performance
- All product components comply with United States Pharmacopeia (USP) <88> Class VI 70°C Biological Reactivity Tests, in vivo
The Emphaze™ AEX Hybrid Purifier is an all-synthetic, multi-mechanism clarifying product that contains a Q-functional anion exchange media and a fine particle, bioburden reduction membrane. This product can substantially reduce turbidity, DNA, HCP and bioburden for improved downstream purification.
The 3M™ Emphaze™ AEX Hybrid Purifier is created using numerous 3M proprietary technologies.
Robustness performance defines our Emphaze™ AEX Hybrid Purifier. Users may see substantial reductions of DNA by more than 99.99%, as well a reduction in host cell proteins (HCP) of 25-35%. This clarifying product may also reduce bioburden by more than 99.9999% of Brevundimonas diminuta and turbidity reduction to often less than 5 NTU. The mAb recovery is often equal to or greater than 95%. These attributes may contribute to enhancing the contaminant clearance performance of protein A columns.
Other applications include: Vaccine production & Blood fractionalization
This type of purification is crucial because high levels of DNA may lead to protein precipitation or aggregation — either before or after the protein A column. Similarly, relatively high levels of HCP are seen in perfusion harvest and a large amount of HCP co-elutes with the protein from the Protein A column. The challenge for the downstream purification process is to consistently reduce DNA, HCP and other levels in the final product. Emphaze™ AEX Hybrid Purifier helps meet this challenge by providing consistent reduction of HCP, DNA and other undesirable elements.
How it Works
Emphaze™ AEX Hybrid Purifier is an all-synthetic, multi-mechanism clarifying single-use capsule containing a synthetic Q-functional anion exchange media integrated with a fine particle, bioburden reduction membrane. The anion exchange media is comprised of a quaternary amine hydrogel supported by a fine fiber nonwoven scaffold. Multiple 3M technology platforms were leveraged to produce a hyper-functionalized high purity polypropylene nonwoven containing covalently attached, thermally stable, water soluble polymer. The functional polymer accounts for roughly two-thirds of the mass of the anion exchange media.
The bioburden reduction membrane is a highly asymmetric, high loading capacity polyamide membrane which has distinct zones of decreasing pore size spanning a roughly 20X range and terminating with a 0.2 µm bioburden reduction rated pore size. All components of the Emphaze™ AEX Hybrid Purifier are compliant with United States Pharmacopeia (USP) <88> Class VI 70°C Biological Reactivity Tests, in vivo.
