​

Blue dextran is synthesized from controlled dextran fractions by reacting with Cibacron blue F3GA. After purification from non-bound dye, products are controlled for molecular weight, solubility, degree of substitution, free dye and loss on drying. TdB Labs offer blue dextran in a wide variety of molecular weights, ranging from 5 kDa to 2000 kDa.

​

Structure

Dextran is a polysaccharide derived from the bacterium Leuconostoc mesenteroides B512F; and consists of an α-D-(1 – 6) linear glucan with a low content (ca. 5%) of side chains linked to 3-carbon of glucose. The dextran is then labelled with Cibacron blue F3GA.

​

Storage and stability

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

​

Solubility

Blue dextran dissolves freely in water.

​

Applications

Blue dextran has long been used as a void volume marker in chromatography. Blue dextran can also be used as a molecular marker.
