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.

FITC-Inulin (FI)

FITC-Inulin (FI)

FITC-inulin is synthesized by reacting fluoresceinyl isothiocyanate (FITC-single isomer) with inulin (from dahlia tubers). The product is a yellow powder which is soluble in water. However since inulin tends to form crystalline aggregates, it is often necessary to heat the solution up to 60 degrees C to achieve complete solubility. Dilute solutions will remain clear on standing but concentrated (10%) may form crystalline precipitates. The molecular weight as determined by Size Exclusion Chromatography calibrated with dextran standards is approximately 5000. Since dextran and inulin have different hydrodynamic volumes, this value is not absolute.
