Looking for an expert on Dextran Derivatives? We produce, analyse and develop custom products for your project.
TdB Consultancy AB is a Swedish biotech company specialized in the development and manufacturing of dextran derivatives. In addition, we have expertise in most aspects of polysaccharide chemistry. This includes not only synthesis but also chemical and physical characterization; our latest addition is a GPC system equipped with light-scattering, viscosity and refractive index detection.
We specialize particularly in the synthesis of fluorescent derivatives of polysaccharides. We offer derivatives labelled with FITC, TRITC, ATTO™-dyes and our proprietary Antonia Red™-dye. Our portfolio consists of more than 30 product groups, of which 20 are fluorescent.

All products from TdB Consultancy are of premium quality. Our polysaccharide derivatives have a low polydispersity (PD) and high purity. This is especially important for permeability studies; a low PD gives much more reliable and reproducible result. Using TdB Consultancy products will help our customers achieve their research goals.
All our standard products are of technical grade. Please contact us if you are interested in products of higher purity. Possible applications of high purity products are for example as part of medical devices. You can read more about our custom specific products here.
Our products are employed widely in Life Sciences ranging from permeability studies, cell preservation, animal studies to applications in processing of clinical products. Dextrans are also used in diagnostic kits and as molecular markers.
We can now offer a series of analyses specific to charged and uncharged dextran and Polysucrose derivatives. This includes molecular weight determination using GPC (gel permeation chromatography), determinations of degrees of substitution for dextran sulfates.Read more here
