DEAE-Dextran (C09-0854-008)

DEAE-dextran is a cationic derivative of dextran. IT is produced by introducing cationic (positively charged) diethylaminoethyl groups into selected dextran fractions. All batches are checked for molecular weight, degree of substitution and loss on drying. Aladdin produce DEAE-dextran from 4 kDa to 2000 kDa. DEAE-dextrans are supplied as a white hygroscopic powder.StructureDEAE-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).ApplicationDEAE-dextrans are used in various areas, for example as adjuvants for vaccines, in transfection techniques and viral infectivity, and for stabilisation of proteins (enzymes).
