Heparin sequencing

LC/MS Sequencing Approach for Highly Sulfated Heparin-Derived Oligosaccharides

Heparin sequencing brings structure to the function of complex oligosaccharides.

H is a highly sulfated linear polysaccharide that was discovered in 1916 as an anticoagulant and has been used clinically since 1935 (see ref. 1 for review). The anticoagulant activity of heparin results from its binding to the serine protease inhibitor, antithrombin III (ATIII) (2, 3). Heparin binding causes a conformational change in ATIII that results in enhanced inhibition of thrombin and o...

Heparin induced thrombocytopenia

Abstract Background and Objectives Heparin is still a commonly used anticoagulant in prophylaxis and treatment of thromboembolic events. Heparin-induced thrombocytopenia (HIT) is a life-threating adverse drug reaction of heparin. The diagnosis of HIT is made based on two important criteria, firstly clinical evaluation and secondly laboratory testing. In this comprehensive review, the authors w...

A strategy for rapid sequencing of heparan sulfate and heparin saccharides.

Sulfated glycosaminoglycans (GAGs) are linear polysaccharides of repeating disaccharide sequences on which are superimposed highly complex and variable patterns of sulfation, especially in heparan sulfate (HS). HS and the structurally related heparin exert important biological functions, primarily by interacting with proteins and regulating their activities. Evidence is accumulating that these ...

Sequencing of 3-O sulfate containing heparin decasaccharides with a partial antithrombin III binding site.

Heparin- and heparan sulfate-like glycosaminoglycans (HLGAGs) represent an important class of molecules that interact with and modulate the activity of growth factors, enzymes, and morphogens. Of the many biological functions for this class of molecules, one of its most important functions is its interaction with antithrombin III (AT-III). AT-III binding to a specific heparin pentasaccharide se...
