Abstract: A method for the simultaneous measurement of proteolylic enzyme generation and clot strength in plasma or whole blood or any appropriate biological sample derived from blood. The measurement method encompasses the use of a detectable substrate which includes a moiety that can be released upon reaction with the targeted proteolytic enzyme, and elements for measurement of an increase in viscosity of clot strength.

Abstract: The invention relates to a method for in vitro determining thrombin activity in a sample wherein the sample is a blood sample and thrombin generation is measured by the steps of: —contacting a layer of said sample with a fluorogenic substrate of thrombin, wherein said layer has a thickness within a range of 0.05 to 5 mm and a surface within a range of 10 to 500 mm2; —allowing thrombin to generate in said sample; —measuring the fluorescence emitted from the surface of the layer, by the fluorescent group released from the fluorogenic substrate as a result of enzymatic action of generated thrombin on said fluorogenic substrate.

Abstract: The present invention relates to the field of blood clotting. Specifically, the invention relates to particular inhibitors of artificial activation of the blood clotting process through contact with foreign surfaces.

Abstract: Disclosed is a method for measuring thrombin generation in a whole blood sample. The whole blood sample may be applied forthwith, without prior processing. The blood cells and blood plasma in the whole blood sample are separated by (lateral) flow migration. Also disclosed is an assembly of a sample support and a device dedicated to measure thrombin generation in a whole blood sample. Advantageously, the sample support comprises a separator medium allowing separation of whole blood into blood cells and blood plasma by means of (lateral) flow migration.

Abstract: A method of determining the course of enzyme activity that is variable in time, wherein the activity is probed by conversion of a substrate of the enzyme, includes, in a selected test set up and for a determined substrate of the enzyme, determining the velocity of signal production (dFdiag/dt) resulting from a time curve of the signal (Fdiao=f(A)) obtained from splitting the substrate when it is contacted with a determined initially fixed concentration of the enzyme (E) and providing a “diagnostic plot” with the values of (dFdiag/dt) against the signal (Fdiag) and determining whether the diagnostic plot is either a straight line or a parabola and in the same test conditions, for a given test sample, determining the signal production (Fexp) resulting from splitting the substrate by the enzyme generating in and/or disappearing from the sample and providing the time curve of signal Fexp=f(t); and transforming the obtained experimental value of the signal (Fexp) into an ideal value (Ftransf).

Abstract: A method for determining the endogenous thrombin potential of a sample having a total anticoagulant activity of or equivalent to at least 0.07 U ISH/ml, includes using a thrombin substrate or a salt thereof that is soluble in the sample to determine the ETP of the sample. Suitable thrombin substrate include those of the formula P-Val-Xaa-S, in which P is an amino protective group, that is non-aromatic and polar, Val is a valine residue attached via a peptide bond to Xaa, Xaa is an amino acid residue comprising a terminal guanidino group or ureido group separated by at least 2 carbon atoms from the peptide backbond the amino acid residue is attached to S and S is a signal group such as a chromophore that can be enzymatically hydrolyzed.

Abstract: In a method of determining heparin content, a known amount of thrombin (FIIa) or activated coagulation factor X (FXa) is added to a mixture which comprises a known concentration of chromogenic substrate (S), a known concentration of antithrombin (AT) and a sample having an unknown heparin concentration. The amount of FIIa or FXa is chosen such that at most 20%, of the S present is reacted during the period which the AT needs to deactivate all the FIIa or FXa present. The final concentration of the reacted chromogenic substrate p-nitroanilide ([pNA].sub.final) is determined after completion of the reactions, and the [pNA].sub.final is used to determine the rate constant (k.sub.dec) of the reaction of FIIa or FXa with AT using the relationship: ##EQU1## The heparin concentration in the sample can then be determined using the value of k.sub.dec from a predetermined calibration curve of k.sub.dec against heparin concentration.

Abstract: A chromogenic assay for determination of blood coagulation Factor VIII:Ca, using an indicator of Factor Xa simultaneously as a measure of Factor VIII:Ca concentration and as an inhibitor of Factor Xa. This technique can be applied to measure the concentration of an activating enzyme using the rate of conversion of the indicator molecule of the product of that enzyme as an indirect indicator of enzyme concentration.
