Abstract

In this chapter, we describe an original protocol based on ITC experiments and data analysis with the software AFFINImeter to get information of heparin-AT interactions relevant for the elucidation of the anticoagulant activity of heparins. This protocol is used to confirm the presence of the bioactive pentasaccharide with anticoagulant activity in heparins and to determine the amount of this pentasaccharide in the sample. Here we have applied this protocol to the characterization of low molecular weight heparins.
