Structure

DEAE-dextrans are synthesised from controlled dextran fractions by reacting with DEAE-chloride. The predominant substituent is the single tertiary group (blue) but this may react further to yield a “tandem” group containing a quaternary amine as well as the tertiary amine. A titration curve reveals the proportions (Fig.2 in datafile).

Storage ａnd stability

DEAE-dextran is stable for more than 6 years when stored dry in well-sealed containers at ambient temperature.

Solubility

DEAE-dextran dissolves readily in water.

Application

DEAE-dextrans are used in various areas, for example as adjuvants for vaccines, in transfection techniques ａnd viral infectivity, ａnd for stabilisation of proteins (enzymes).
