Dextran Sulfate 8000 Na is a polyanionic derivative of dextran, produced by the esterification of the glucose polymer (glucan polysaccharide) with chlorosulphonic acid. Dextran fractions are characterized by their average MW and MW distribution with predominantly 1-6 glycosidic bones and 5% or less of 1-3 branching. Each base dextran polymer has characteristics unique to the specific strain of bacteria from which is was derived. In addition to variables in molecular weight and branching, the level of sulfonation adds to the unique character and performance of the finished product in terms of its intended end use. Dextran Sulfate 8000 Na, 8000 MW is used in the solubilization and purification process of protein molecules intended for use in a final drug product. Dextran is neutral in pH and soluble in water. It is easily filtered and biodegradable.

D-Galactose, plant derived is intended for use upstream and downstream in biological drug manufacturing processes. For this purpose BioSpectra has categorized our product as an excipient though one of the primary functions is to be used as a nutrient in mammalian cell culture media. Given the sensitivity of these cells in regard to growth, BioSpectra’s D-Galactose is manufactured to meet high purity specifications and low bioburden and endotoxin demands.
