WebThe popularity of Sepharose™ Fast Flow ion exchange (IEX) chromatography resins reflects the important role they play in protein purification today. The reliability and well-documented performance of the resins have made them a common choice for capture and intermediate purification of proteins in both research and industry. WebUse Sepharose Fast Flow media for purification of proteins. Use Sepharose Fast Flow for capture or intermediate purification steps that require good resolution (flows up to 300 cm/h). Use a weak ion exchanger such as DEAE, CM or ANX Sepharose Fast Flow, if a strong ion exchanger (substituted with Q, S or SP) does not give the required selectivity.
