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.

Products

CM -dextran

CAS Number: 39422-83-8

CM-dextran consists of a dextran backbone substituted with anionic carboxymethyl substituents. TdB Labs produce CM-dextrans from 4 kDa to 150 kDa.

CM -polysucrose

Carboxymethyl-polysucrose (CM-polysucrose) consists of polysucrose substituted with anionic carboxymethyl groups. TdB Labs produce CM-polysucrose with a mean molecular weight of 70 kDa.

DEAE -dextran

CAS Number: 9015-73-0

DEAE-dextran is produced by introducing cationic diethylaminoethyl groups into selected dextran fractions. TdB Labs produce DEAE-dextran from 4 kDa to 2000 kDa.

DEAE -polysucrose

DEAE-Polysucrose is a polysucrose substituted with cationic diethylaminoethyl (DEAE) groups. The DEAE-polysucrose from TdB Labs is derived from a polysucrose with an average molecular weight of approximately 70 kDa.

Lysine -dextran

Lysine-dextrans are dextran derivatives carrying both free primary amines and free carboxylates. TdB labs produce lysine-dextran from 4 kDa to 500 kDa.

Phenyl -dextran

Phenyl-dextrans are synthesised from selected controlled dextran fractions by reacting with an appropriate epoxide. TdB labs produce phenyl-dextran with a mean molecular weight of 5 kDa, 40 kDa and 150 kDa.

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.

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).
