CAS No. 87915-38-6
Blue dextrans are now available in eight different molecular weight ranges. Blue dextrans are synthesised from controlled dextran fractions derived from Leuconostoc mesenteroides by reacting with Cibacron blue F3GA. After purification from non-bound dye the products are controlled for solubility, degree of substitution, free dye and loss on drying. The low molecular weight blue dextrans (BD5, BD10 and BD20) require purification by chromatographic methods during production and are therefore more expensive than the larger ones.
A Specification may be obtained on request.
The products are designated by the approximate molecular weights of the final products. Thus, for example, the product BD5 has a molecular weight of approx. 5000. The actual molecular weight is determined by GPC. This value is supplied with the COA.
