HiTrap ANX (high sub) FF is prepacked with ANX (high sub) Sepharose Fast Flow, and is a weak anion exchanger for small scale purification of higher molecular weight protein as well as screening of binding and elutions conditions.

• Convenient and affordable for fast, easy ion exchange separations either alone or connected in series.
• The industry standard for ion exchange chromatography.
• High flow rates and good scale-up potential.
• Use a weak ion exchanger if the selectivity of a strong ion exchanger is insufficient.
• Predictable scale-up

Q, SP, DEAE, and CM Sepharose Fast Flow are based on a robust, 6% highly cross-linked beaded agarose matrix with good flow properties and high loading capacities. ANX Sepharose 4 Fast Flow (high sub) is based on 4% highly cross-linked beaded agarose. This results in a resin with higher porosity, which is particularly useful for the purification of high molecular mass proteins.

The active end of the charged group is the same for DEAE Sepharose Fast Flow and ANX Sepharose Fast Flow (high sub), the difference is the length of the carbon chain of the charged group. DEAE Sepharose Fast Flow has a diethylaminoethyl-group bound to the agarose whilst ANX Sepharose 4 Fast Flow (high sub) has a diethylaminopropyl group attached.
