DEAE-dextrans

CAS No. 9015-73-0

DEAE-substituents have been introduced into a range of dextran fractions. The chemical reaction introduces two types of substituents.

The predominant substituent is the single tertiary group (blue) but this reacts further in some cases to yield a "tandem" group (red) containing a quarternary amine as well as the tertiary amine. A titration curve reveals the proportions (Fig.2). 

DEAE-dextrans are supplied as a white hygroscopic powder which are readily soluble in water and salt solutions. The powder is stable at room temperature for more than three years providing it is stored in well-sealed containers in the dark.

DEAE-dextrans are used in various areas: 

  • As adjuvant for vaccines 
  • In transfection techniques and viral infectivity 
  • For stabilisation of proteins (enzymes)
