IEX Sepharose Fast Flow labpacks and prepacked columns

GE Healthcare Data file -77- Ion exchange chromatography IEX Sepharose Fast Flow labpacks and prepacked columns The popularity of Sepharose Fast Flow ion exchangers reflects the leading role they play in protein purification today. Their reliability and well-documented performance, and regular additions to the basic range, has ensured that they remain the first choice for capture and intermediate purification of proteins in both research and industry. Sepharose Fast Flow ion exchangers offer many practical advantages: High binding capacity and excellent flow properties High chemical and physical stabilities Reliable and reproducible Easy and effective CIP/sanitization Convenient HiPrep and HiTrap prepacked columns Predictable scale-up Ion exchange chromatography Ion exchange chromatography is probably the most frequently used and versatile method for fractionating proteins and peptides; even those with small differences in charge. Furthermore, binding and elution conditions are easy to optimize, resulting in fast separations that are reproducible and cost-effective to scale up. The technique is based on reversible interactions between charged molecules and immobilized ion exchange groups of opposite charge. The charged molecules bind to the separation medium at low ionic strength and are then eluted with a salt or gradient. Continuous gradient elution is most often used when good resolution is needed, while simple stepwise gradient elution is employed for sample preparation, group separation, or concentration. Fig. Sepharose Fast Flow ion exchangers, available in lab packs and prepacked columns, continue to play a leading role in preparative protein separations. Sepharose Fast Flow ion exchangers include media that are called weak (CM, DEE, and NX) or strong (SP and Q). The binding capacity of weak ion exchangers varies with considerably more than that of strong ion exchangers, which might affect selectivity. In contrast, the ligands of strong ion exchangers remain charged and consistently maintain high capacity over broad working ranges.

Media characteristics Sepharose Fast Flow ion exchange media comprise SP Sepharose Fast Flow, CM Sepharose Fast Flow, Q Sepharose Fast Flow, DEE Sepharose Fast Flow, and NX Sepharose Fast Flow (high sub). SP, CM, Q, and DEE are based on a robust, % highly crosslinked beaded agarose matrix with excellent flow properties and high loading capacity. Typical linear flow rates of 3 to cm/h through a 5-cm high bed at a pressure of bar, give fast separation cycles, which is especially important early in purification when rapid enrichment is required. For washing and equilibration, flow rates extend up to 75 cm/h. NX Sepharose Fast Flow (high sub) is based on a % highly cross-linked agarose matrix. This results in a medium with higher porosity, which is particularly useful for purifying high molecular weight proteins. Like the other Sepharose Fast Flow ion exchange media, NX has high flow rates for processing. Table.

Their functional ion exchange groups are attached to the matrices via chemically stable ether linkages. The main media characteristics are listed in Table. Figure shows the working ranges of the ion exchangers as titration curves, that is, the ranges over which the functional groups are charged. Packing in laboratory columns Sepharose Fast Flow media are supplied in laboratory packs for users who prefer the flexibility of packing columns of their choice. Straightforward and well-proven recommendations for packing, operation, and maintenance are included in the instructions supplied with each pack. Columns and accessories from the XK range are recommended. Prepacked Sepharose Fast Flow ion exchange columns y providing extra speed, convenience, and reproducibility, prepacked columns extend the usefulness of Sepharose Fast Flow ion exchangers. In addition, ÄKTdesign TM chromatography systems include preset method templates for these prepacked columns, which further simplifies operation, especially reproducibility, and saves time. ll five media are supplied in two types of column: HiPrep / ( ml) and HiTrap, the latter available in -ml and 5-ml sizes. The five HiTrap -ml columns are also included in HiTrap IEX Selection Kit together with SP Sepharose XL and Q Sepharose XL. HiPrep / columns HiPrep / SP FF, HiPrep / CM FF, HiPrep / Q FF, HiPrep / DEE FF, and HiPrep / NX FF (high sub) are prepacked, ready to use IEX columns. They are simple to operate and compatible with single pump configurations as well as ÄKTdesign systems. Rapid enrichment during the initial capture of proteins from the start material is an ideal application for any of the columns named above. HiPrep / columns are made of polypropylene, which is biocompatible with biomolecules. Its bed height of cm gives a volume of ml. The supplied set of connectors makes it easy to connect the columns to different equipment. See Table for the main characteristics of the HiPrep / column. Note that HiPrep columns cannot be opened or repacked.

The -ml column is often used for method screening to quickly establish optimal binding and elution conditions. Its fast and simple operation is ideally suited to this role, as well as to small-scale purifications. The larger 5-ml column is an excellent choice for group separations and sample concentration, and when the purification method has been established and larger amounts of protein need to be purified. For quick scale-up of purification, two or three HiTrap columns can easily be connected in series. Further scale-up can be done on HiPrep / columns, see Figure. HiTrap columns are made of polypropylene, which is biocompatible with biomolecules. The column is delivered with a stopper on the inlet and a snap-off end on the outlet. ll necessary connectors are included for connection to different systems, as well as to a laboratory pump and a simple syringe. Note that HiTrap columns cannot be opened or repacked. Table 3.

HiTrap IEX Selection Kit The -ml version of all five HiTrap columns named above is also included in HiTrap IEX Selection Kit, which also contains SP Sepharose XL and Q Sepharose XL. In offering seven well-known media in an easy-to-compare format, this kit offers a fast, simple, and convenient way to decide which ion exchange medium and ligand is best for a given application. In other words, it is a useful tool in speeding the development of an optimized ion exchange separation. For more information about the kit, request Data file HiTrap IEX Selection Kit, code no. --. Choice of buffer s noted earlier, ion exchange chromatography is based on reversible interactions between charged molecules and immobilized ion exchange groups of opposite charge. Charged molecules bind to the separation medium at low ionic strength and are then eluted with a salt or gradient. To avoid local disturbances in caused by buffering ions participating in the ion exchange process, select an eluent with buffering ions of the same charge as the substituent groups on the ion exchanger. See Figures and 5 for a selection of standard aqueous buffers and Table for a selection of volatile buffers. Chemical stability Good chemical stability allows the use of effective cleaningin-place (CIP) schemes that result in high recoveries over many purification cycles. Likewise, it allows regular sanitization to hinder microbial growth and maintain a high level of hygiene. oth CIP and sanitization thus promote good economy and are therefore key factors to consider when selecting ion exchange media and prepacked columns for preparative applications.

For CIP, regular washing with.5 to. M sodium hydroxide should be sufficient to remove most contaminating material, although very hydrophobic molecules might bind so tightly that they must be eluted with organic solvents like 7% ethanol or 3% isopropanol, or with strong detergents. General CIP and sanitization protocols for SP Sepharose Fast Flow, CM Sepharose Fast Flow, Q Sepharose Fast Flow, DEE Sepharose Fast Flow, and NX Sepharose Fast Flow (high sub) are supplied with the media. Note that specific protocols should be developed according to the nature and condition of the start material..5 5 7 9 N-methyl piperazine Piperazine bis-tris bis-tris propane Triethanolamine Tris pka (5 C).75 5... 7.7.

The excellent availability of suitable equipment also contributes to their effective use; especially as systems in the ÄKTdesign platform have method templates for both HiPrep and HiTrap columns. Ease of scale-up is a key practical benefit of working with any Sepharose Fast Flow ion exchanger.
