CAS Number: 87915-38-6 Blue dextrans are synthesised 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 -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 dextrans are stable for more than 6 years when stored dry in well-sealed containers at ambient temperatuSolubility 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.Can™t find what you are looking for?
