    摘要: For the determination of antithrombin-BM an antithrombin-BM-cofactor, thrombin and a determinable thrombin substrate are added to a sample solution and the splitting of the thrombin substrate is determined as a measure for the antithrombin-BM activity, whereby heparin, xylan, .lambda.-carrageenan, dextran sulphate, mucopolysaccharide polysulphuric acid esters, pentosan polysulphates or short-chained heparin derivatives produced by the chemical or enzymatic splitting of heparin are used as cofactors.
