Dextran Sulfate
Blue dextran
TdB Labs AB is a family owned Swedish biotech company. We are specialised in the development and manufacturing of dextran derivatives and other polysaccharides. We offer fluorescent derivatives with FITC, TRITC, ATTO™-dyes and our proprietary Antonia Red™-dye. Our non-fluorescent derivatives include e.g. different variants of dextran sulfate, including dextran sulfate sodium (DSS) for colitis.
Thanks to our capability to offer customised polysaccharides, TdB Labs can offer products that cannot be found anywhere else. Making customised products entails not only chemical synthesis but also extensive quality control aspects as well as technical documentation.
Our products are employed widely in Life Sciences ranging from permeability studies, cell preservation and animal studies to applications in processing of clinical products. Our polysaccharide derivatives can also be used in diagnostic kits and as molecular markers.
With our analytical service, we provide a comprehensive service along with technical support. We offer a series of analyses specific to charged and uncharged polysaccharides. This includes molecular weight determination using gel permeation chromatography (GPC), also called size exclusion chromatography (SEC).
