About the product
The 3M™ Polisher ST is a fully encapsulated single-use anion exchange (AEX) product. It is intended to reduce host cell protein, viruses, and other negatively charged contaminants in a flow-through polishing chromatography mode in biopharmaceutical process streams. The 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.
Product details
- Unaffected by process fluid turbidity up to 40 NTU.
- The 3M™ Polisher ST is a single use multi-mechanism membrane adsorber which contains a Q-functional anion exchange non woven media and guanidinium functionalised membrane. This product removes residual turbidity, DNA and HCP and provides robust virus clearance for improved downstream/polishing purification.
- Single-use technology as a cost-efficient option to increase biomass production by delivering high purity and yield in the downstream polishing unit operation in therapeutic recombinant protein process in biologically relevant operating conditions.
- Replaces downstream AEX polishing column for reduction of HCP and virus in a salt tolerant (ST) manner as a single-use solution.
- Provides DNA reduction in a salt tolerant (ST) manner compared with conventional Q-functional AEX resins.
