Abstract Thermal stabilisation of native antithrombin-III (AT), determined using differential scanning fluorimetry, correlated with the anticoagulant activity of heparin and heparin-related saccharides. Similar conformational changes were induced in native AT by a variety of active and inactive heparin-related sulfated carbohydrates, measured in solution using synchrotron radiation circular dichroism, and their anticoagulant activities. Measurement of native AT stabilisation provides a convenient assay for prospective anticoagulants and represents an additional parameter by which to compare biosimilar heparins.
