CAS Number: 9015-73-0 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. TdB Labs produce DEAE-dextran from 4 kDa to 2000 kDa. DEAE-dextrans are supplied as a white hygroscopic powder.Can’t find what you are looking for? We can always produce a customised product for you. Structure DEAE-dextran is synthesized 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 stabilization of proteins (enzymes).
