TOYOPEARL DEAE-650 media are weak anion exchangers for blood fractionation and other biomolecule purification. They can be used for high throughput capture, intermediate purification, and polishing process steps.
If a greater level of resolution is required, TSKgel DEAE-5PW resin should be used. Selectivity remains the same.
