Other derivatives and polysaccharides

Apart from dextran derivatives, TdB Labs also produce derivatives of other polysaccharides such as polysucrose, inulin, hyaluronic acid, trehalose and hydroxyethyl starch. Our product portfolio includes charged polysaccharides with functional groups like carboxymethyl (CM), diethylaminoethyl (DEAE) and quaternary-ammonium (Q).

Applications

Polysaccharide derivatives have multiple usage areas. For example, they can be sued for coating of medical devices, as stabilisers for proteins and hydrogels, as adjuvants in vaccines and more.

Other derivatives and polysaccharides

Q -dextran

Q-dextrans are cationic derivative of dextran synthesised by reacting dextran fractions with 2,3-epoxypropyltrimethylammonium chloride. TdB Labs produce Q-dextran from 4 kDa to 150 kDa.

Other derivatives and polysaccharides

Polysucrose

CAS Number: 26873-85-8

Polysucrose molecules are highly branched, and the high content of hydroxyl groups leads to very good solubility in aqueous media. Polysucroses behave as an ideal neutral sphere and displays excellent biocompatibility. TdB Labs produce polysucrose from 20 kDa to 1000 kDa.

Hyaluronic acid products

Hyaluronic acid is a polysaccharide composed of alternating β(1-3) glucuronide and β(1-4) glucosaminide units derived from rooster combs or Streptococcus equi. TdB Labs supply derivatives of either of these qualities labelled with fluorescein (F-HA) or tetramethylrhodamine (T-HA).
