Heparine oligosaccharide of 18 sugar units (9 disaccharides), digested by Heparinase I from purified HP glycosaminoglycan

These oligosaccharides have been prepared by high resolution gel filtration of partial heparin lyase (Heparinase I) digestion of high quality heparin. General formula* ∆HexA,2S - GlcNS,6S– (IdoUA,2S – GlcNS,6S)n n = number of disaccharide units. *Although the main disaccharide unit in these products is IdoUA,2S – GlcNS,6S, (approx 75%) saccharides in each size class show some variation in degree and pattern of sulphation. Uronic acid (HexA) at the non-reducing end of the oligosaccharides has a C4-C5 double bond as a result of the endolytic action of bacterial heparin lyase.
