1 GE Healthcare Life Sciences Data file AC Gel filtration Superose High-performance Columns Superose prepacked columns are designed for highperformance, laboratory-scale separations of proteins and other biomolecules according to size. Due to its wide separation range, Superose is a versatile medium. Superose prepacked columns give fast and reproducible separations with good resolution. The columns are ideal for the final polishing step in a purification procedure, where the remaining trace contaminants are removed. Superose columns offer: High-resolution separations of proteins and other biomolecules according to size Wide separation range separations in two molecular weight ranges from 1 up to 5 million M r Excellent reproducibility and durability Laboratory scale purifications, from µg to mg Media characteristics Superose prepacked columns are available with two different media: Superose 6 or Superose 12. Table 1 summarizes the main characteristics of Superose. Good resolution separations of proteins and other biomolecules according to size Gel filtration separates biomolecules according to molecular size. The method is ideal for the final polishing step in a purification procedure when sample volumes have been reduced. Since the composition of the buffer does not Fig 1. Superose 6 GL and Superose 12 GL prepacked Tricorn columns. directly affect the separation, elution conditions such as ph and salt concentration can be varied to suit the sample or the requirements for the next step. A high-performance medium like Superose is invaluable when it is necessary to obtain protein preparations free of dimers and other aggregates, for example before crystallization trials. Superose 6 and Superose 12 have an average bead size of 13 µm and 11 µm respectively, and are designed for laboratory-scale separations. The small bead size gives good resolving capacity. Superose 6 prep grade and Superose 12 prep grade have an average bead size of 3 µm and are suitable for larger scale separations.

Superose complements Superdex by offering wider molecular weight separation ranges. A comparison between Superose and Superdex is shown in Figure 2. Superose 6 is especially valuable for its ability to separate very large biomolecules according to size.

Separation ranges (globular proteins) of Superose and Superdex gel filtration media. High chemical and ph stabilities Superose is formed from cross-linked agarose matrices that have high chemical and broad ph stabilities (short-term ph 1 to 14, long-term ph 3 to 12). Superose media can be used with all common aqueous buffers and are unaffected by detergents such as 1% SDS, chaotropic salts or dissociating agents such as 8 M urea or 6 M guanidine hydrochloride, and organic solvents such as 3% acetonitrile. The media can withstand strong bases (such as.2 M NaOH) and strong acids (such as 1 M acetic acid or 7% formic acid) allowing the use of stringent cleaning procedures, which are essential to maintain column efficiency without reducing the lifetime of the column. Column characteristics Superose media are prepacked in high performance glass columns. Both column types Tricorn (GL) and Precision (PC) are made of glass, which allows visual inspection of the gel bed. All parts of the columns are biocompatible. Table 2 shows the characteristics of Tricorn and Precision columns prepacked with Superose. Tricorn columns are simple to use, with fittings for simple connection to ÄKTAdesign and other high-performance LC systems, and can be run according to their specifications where the systems have the appropriate pressure capacity. Precision Columns were designed for SMART systems, but the Precision Column Holder allows use of the columns with a variety of high-performance systems. All parts of the columns are biocompatible AC

Excellent reproducibility and durability Reproducible results are essential in all research. The long working life and high reproducibility of Superose prepacked columns, both run-to-run and column-to-column, are a result of optimized column design, the stable nature of Superose, and well-proven, reliable column packing procedures. These are in addition to the controlled column manufacturing and media synthesis, and strict quality control testing of every production batch of Superose and each prepacked column. Figure 3 shows the separation of protein standards on Superose 12 1/3 GL before and after 21 consecutive runs. Operation Choice of eluents Eluents can be chosen freely to improve recovery from separations of crude sample or to overcome solubility problems. For example, chaotropic agents and detergents can be used to improve the solubility of membrane proteins..15 M NaCl, or a buffer with equivalent ionic strength, is recommended to avoid ph-dependent non-ionic interactions with the matrix. Sample volumes The quality of a gel filtration separation is largely independent of sample concentration, but to achieve good resolution, the sample volume should be less than 5% of the total column volume. Sample volumes between.1% and 1.% of the bed volume (25 to 25 µl) give the highest resolution in Superose 1/3 GL columns. For more information see Table 2.

4 Large-scale preparative separation To handle larger sample volumes it may be necessary to pack larger columns. Superose 6 prep grade and Superose 12 prep grade are available in lab packs for use when larger column volumes are required. Superose prep grade media have an increased bead size to give a similar selectivity to prepacked Superose columns, but easier column packing and tolerance to crude samples. Figure 4 shows selectivity curves for Superose prep grade (3 µm), compared to Superose 6 (13 µm) and Superose 12 (1 µm).

Applications Separation of standard proteins Superose 6 1/3 GL and Superose 12 1/3 GL are prepacked columns produced under optimum conditions to give the highest column efficiency and performance. These columns offer good resolution and broad selectivity gel filtration over a broad molecular weight range, as shown in Figure 5.
