Process Media


TOYOPEARL SuperQ-650M resin is a strong anion exchanger for biomolecule purification. This resin is composed of a base material of hydroxylated methacrylic polymer beads that have been functionalized with quaternary amine (Q) strong anion exchange groups.  This resin has a 100 nm pore size and a 65 µm bead size.

 TOYOPEARL SuperQ-650M resin is best used for high throughput intermediate purification and polishing process steps. If greater resolution is needed, the smaller particle size TOYOPEARL SuperQ-650S or TSKgel SuperQ-5PW resins may be used. As both the TOYOPEARL SuperQ-650 and TSKgel SuperQ-5PW resins use the same ligand and backbone chemistry, the selectivity will be unchanged between the two resin types.

Benzyl Alcohol Removal


A 2% solution of benzyl alcohol in water has been identified as a suitable alternative to 20% ethanol as a preservative in resin storage solutions. A sample of TOYOPEARL SuperQ-650M resin was prepared by adding 100 mL of aqueous 2% benzyl alcohol to 100 mL of suction filtered resin. A 100 mL aliquot of DI water was added to the filtered resin and stirred to make a slurry. This resin/ DI water slurry was allowed to stand for 5 minutes and was then suction filtered to remove the supernatant. This procedure was repeated 14 more times, for a total of 15 washes.

Samples of the filtered supernatant from the TOYOPEARL SuperQ-650M resin was taken after the 5th, 10th, and 15th washes and analyzed for benzyl alcohol concentration. As demonstrated in the figure, a 2% benzyl alcohol solution can be removed from the TOYOPEARL SuperQ-650M resin by thorough washing with DI water.
