Our standard product portfolio consists of both fluorescent and non-fluorescent polysaccharide derivatives. Our focus is dextran derivatives, but we also offer derivatives of other polysaccharides such as polysucrose, inulin, hyaluronic acid, trehalose and hydroxyethyl starch.

Our products are widely employed within the life science sector. Our fluorescent derivatives are mainly used for studies of permeability and microcirculation in cells and tissues, for studies of drug delivery or as molecular size markers. Our fluorescent products include derivatives labelled with FITC,
TRITC, ATTO™-dyes and our proprietary Antonia Red™-dye.

Our non-fluorescent derivatives include e.g. dextran sulfates and charged polysaccharides with functional groups like carboxymethyl (CM), diethylaminoethyl (DEAE) and quaternary-ammonium (Q). One of our most popular products is dextran sulfate sodium (DSS), which has been used to induce colitis in mice and rats for more than 20 years. Dextran sulfates of lower molecular weights are often used as a cell media additive or as stabilisers. Our blue dextran is often used as a void volume marker in chromatography. Our phenyl-dextran may be used in the preparation of hydrophobic gels and coatings.

We can provide Pharmaceutical grade purity on demand if you plan to use our products as starting or Raw Matrials for the pharmaceutical formulations, medical devices or related. We fulfill requirements from the European Pharmacopoeia (EP) for production and quality for “Dextran for injection” that are in accordance with EDQM certification, including testing for microbial contamination and bacterial endotoxins, and more. Let us know prior to your order if you need PharmaGrade purity.
