    摘要: In order to determine antithrombin III in body fluids by reacting the sample with thrombin and a chromogenic substrate which forms a colour by the action of thrombin and measurement of the colour formed, the reaction is carried out in the presence of denaturing agents or of the tetrapeptide Gly-Pro-Arg-Pro and an oligopeptide is used as the substrate which has a sensitivity to thrombin which is a factor of 5 to 100-fold lower compared With Tos-Gly-Pro-Arg-pNA

    摘要: The present invention provides a process for the photometric determination of protein C and/or protein S activity, especially in plasma, wherein the sample containing the protein C and/or protein S to be determined is incubated with a protein C activator from snake venom with the formation of activated protein C and/or protein S and the decrease of the formation of thrombin from prothrombin brought about by the coagulation factors and the activators thereof is determined by means of a chromogenic thrombin substrate.

    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.

    摘要: The present invention provides an analysis element for the determination of coagulation parameters with the help of a detectable or a detection reaction-initiating substrate of a protease of the blood coagulation system and at least one factor and/or co-factor of the blood coagulation system and a buffer substance, wherein the factor and/or co-factor, together with a water-soluble, non-ionic polymer which does not falsely influence the course of the coagulation cascade, is impregnated on an open, planar composite structure which consists of a material which does not have a disturbing influence on the course of the coagulation.
