Amon-exchange

Adsorption This method is the simplest way to immobilize enzymes. Enzymes can be adsorbed physically on a surface-active adsorbent by contacting an aqueous solution of enzyme with an adsorbent. Commonly employed adsorbents are (Zaborsky, 1973) alumina, amon-exchange resins, calcium carbonate, carbon, cation-exchange resins, celluloses, clays, collagen, colloid-ion, conditioned metal, glass plates, diatomaceous earth, and hydroxyapatite. The advantages of adsorption techniques are as follows ... 

Plasmid DNA can be purified by the classical alkaline lysis/caesium chloride gradient procedure or through rapid methods involving the use of small amon-exchange resin columns (e.g, Qiagen or Nucleobond columns)...
