IEX SepFastTM Large Beads Plus Media

>>Introduction >>Product Charactistics >>Ordering Info >>How to Order


Q , DEAE , SP and CM SepFast Large Beads Plus are a group of ion exchange chromatography media with large particle sizes (100 – 350 μm) and high binding capacity. The base matrix shows excellent flow property and stable physical property.

The above ion-exchange chromatography media is particularly suitable for large-scale purification of biological molecules from viscous and/or crude culture broths or for high speed flow-through polishing applications in which impure components are chromatographically adsorbed from the main product stream.

This group of ion-exchange media has a balanced design among ligand density, loading capacity and separation power of individual components for large-scale biomanufacturing applications. IEX SepFast Large Beads Plus offers increased binding capacity and faster binding kinetics than IEX SepFast Large Beads.

The SepFast Large Beads Plus is made of highly cross-linked agarose grafted with dextran for increased binding capacity. They are very stable to most of the chemical conditions experienced in the bioprocessing industry.
