under the experimental conditions used , the salt concentrations required for elution of the adsorbed enzymes were lower with cellulose than with deae-cellulose , cm-cellulose , or p-cellulose , indicating that ion exchange groups , either cationic or anionic , affected the adsorption , although the ion exchange groups of deae-cellulose , cm-cellulose , and p-cellulose were weakly but definitely functional as ion exchangers even in the presence of high concentrations of the salts .
