Abstract: The present invention relates to a method to improve chromatography beads. More closely, the invention relates to a novel method for production of dextran-containing porous media and chromatography media produced with this method. In the method, the chromatography media is subjected to dextranase-treatment leading to improved pressure-flow properties of the media.
