Premium Quality Dextran Derivatives

Using TdB’s premium products with narrow fractions will give you reliable and reproducible results.

Looking for an expert on Dextran Derivatives? We produce, analyse and develop custom products for your project.

Our core business is dextran and dextran derivatives, but we have expertise in most aspects of polysaccharide chemistry. This includes not only synthesis but also chemical and physical chemical characterisation.

TdB Consultancy specialises particularly in the synthesis of fluorescent derivatives of polysaccharides and apart from the FITC- and TRITC-derivatives, we are at present preparing a new range of fluorophores.
