MacroSep IEX Q

Anion Exchange Resin for Purification of Large Biomolecules

Ion exchange chromatography is an ideal technique for purifying biomolecules with high productivity. As the target substances become larger, the demands on process resins are changing. YMC has developed a new and innovative resin to target large biomolecules and particles such as adeno-associated viruses (AAVs), protein complexes, and plasmid DNA (pDNA): MacroSep IEX Q!

This new strong anion exchange resin offers an optimized macro-porous structure that ensures efficient purification of these molecules. With its high binding capacity for large particles and molecules and high separation efficiency even at elevated flow rates, MacroSep IEX Q is a perfect addition to DSP platforms.
