Abstract
This invention describes materials and methods usable for the purification of polyelectrolytes, such as nucleic acids and proteins. The materials of the invention are separation media that possess pH-dependent groups with pKa value in the range of about 5 to about 7. Separation of the nucleic acids or proteins from a separation medium is effected at a neutral or higher pH.
