Heparin Derivatives

Heparin is a complex polysaccharide composed of repeating disaccharides of uronic acid -> glucosamine. The disaccharide units may be biosynthetically modified as N-acetyl or N-sulfate glucosamine, 2-O-sulfate uronic acid and 6-O-sulfate and/or 3-O-sulfate glucosamine. Heparin Derivatives consist of a group of products derived from heparin, made by one or more chemical modifications. The modifications are designed to change the activity of relevant groups of the molecules, thus to provide a wide range of heparin derivatives for structure-function study and biological activity analysis.

Over Sulfated Heparin
Catalog No. GT6020
Over Sulfated Heparin is a derivative in which all primary hydroxyls in glucosamine residues and a large proportion of secondary hydroxyl groups in disaccharide units have been substituted by O-sulfate esters.

Carboxyl-Reduced Heparin
Catalog No. GT6060
Carboxyl-Reduced Heparin is a derivative in which the carboxyl group of uronic acid residues of heparin have been reduced to alcohols. The disaccharide units in the derivative are either glucose -> glucosamine or idose -> glucosamine.

Periodate-Oxidized Heparin
Catalog No. GT6070
Periodate-Oxidized Heparin is a derivative in which all unsulfated uronic acid residues of heparin are oxidized by periodic acid. After periodate oxidation the newly formed aldehydes are reduced to primary alcohols.

Fully De-O-Sulfated Heparin
Catalog No. GT6011
De-O-Sulfated Heparin is a derivative in which all O-sulfate esters of heparin have been removed without changing the backbone structure. Most of the negative charge contributed by O-sulfates has been eliminated.

2-O-Desulfated Heparin
Catalog No. GT6012
2-O-Desulfated Heparin is a derivative in which only the O-sulfate groups on C-2 of uronic acid residues have been removed. The backbone structure of the derivative is unchanged but all uronic acid residues become unsubstituted.

6-O-Desulfated Heparin
Catalog No. GT6013
6-O-Desulfated Heparin is a derivative in which most of O-sulfate groups on C-6 of glucosamine residues have been removed while most of the 2-O-sulfate / 3-O-sulfate groups are remain intact.

Fully N-Acetylated Heparin
Catalog No. GT6031
Fully N-Acetylated Heparin is a heparin derivative prepared by N-acetylation of De-N-Sulfated Heparin. All disaccharide units in the derivative are uronic acid -> N-acetyl-glucosamine units.

Fully N-Sulfated Heparin
Catalog No. GT6041
Fully N-Sulfated Heparin is a derivative made by N-sulfation of De-N-Acetylated Heparin. The sequence of the disaccharide units in the derivative are exclusively uronic acid -> N-sulfate-glucosamine.

De-N-Sulfated Heparin
Catalog No. GT6030
De-N-Sulfated Heparin is a derivative in which N-sulfate groups of the N-sulfated-glucosamine residues of heparin are removed. The altered disaccharide residues in the derivative become uronic acid -> glucosamine, while the unmodified disaccharide units remain as uronic acid -> N - acetyl-glucosamine.

De-N-Acetylated Heparin
Catalog No. GT6040
De-N-Acetylated Heparin is a heparin derivative in which all N-acetyl groups of the N-acetyl-glucosamine residues of heparin have been depleted. The altered disaccharide unit in the derivative becomes uronic acid -> glucosamine while the unmodified disaccharide unit remains as uronic acid -> N-sulfate-glucosamine.
