IEX Sepharose™ Fast Flow
- For preparative purifications, even when purifying crude samples.
- Available with strong (Q and SP) and weak (DEAE, CM, and ANX) anion and cation exchangers, in bulk quantities and in prepacked HiTrap™ and HiPrep™ columns, as well as HiTrap™ IEX Selection Kit.
- For separation of proteins of all pI values with Q and SP having a high dynamic capacity for proteins over the entire pH range.
- ANX has a different selectivity compared to DEAE, and is applicable for separation of high molecular weight proteins.
- Easy scale-up from HiTrap™ scale to laboratory scale to process scale.
