  • Absorbent medium containing particles of chopped cellulose or agarose sponge material having functional groups
    Patent number: 6723539
    Abstract: An adsorbent medium is prepared comprising particles of a sponge material made of cellulose or agarose carrying functional groups such as diethylaminoethane groups. The particles may be obtained by chopping a larger block of the sponge material. The medium preferably has a water retention value of greater than 6 ml/g and a particle size of 0.5 to 10 mm, and the sponge material may be cross-linked. The adsorbent medium is especially useful for purifying DNA in an aqueous sample.
