摘要:
Provided is a method for purifying α-thrombin and for quantifying α-thrombin and its degradation polypeptides in a liquid proteinatious solution. The method employs a one-step anion exchange chromatography method. The method allows purification and/or quantification of a homogenous post-translationally modified α-thrombin. The method can also be used for purification and/or quantification of β-thrombin.
摘要:
The present invention relates to analytical testing devices including micro-environment sensors and methods for assaying coagulation in a fluid sample applied to the micro-environment sensors, and in particular, performing one or more types of coagulation assays using one or more micro-environment sensors in a single point of care combined test cartridge. For example, the present invention may be directed to test sensor including at least one transducer coated with a polymer layer. The polymer layer comprises a thrombin-cleavable peptide with a detectable moiety.

摘要:
The present invention relates to analytical testing devices comprising a single channel with micro-environment sensors and methods for assaying coagulation in a fluid sample applied to the micro-environment sensors, and in particular, to performing coagulation assays using a single channel with micro-environment sensors in a point of care test cartridge. For example, the present invention may be directed to a sample analysis cartridge including an inlet chamber configured to receive a biological sample and a conduit fluidically connected to the inlet chamber. The conduit includes a sensor chip including a first micro-environment sensor and a second microenvironment sensor, and a fluid lock valve. The sample analysis cartridge further includes a pump configured to push the biological sample over the first micro-environment sensor and the second microenvironment sensor to the fluidic lock valve such that the biological sample is positioned over the first micro-environment sensor and the second micro-environment sensor.

The use of factor Xa in the prevention or treatment in a patient, in particular a human being or an animal, of haemorrhagic events induced by taking anticoagulants.
摘要:
A kit for the determination of the thrombogenic power of human immunoglobulins contained in a biologically acceptable product. Also a process making it possible to determine the thrombogenic power linked to the presence of activated Factor XI and/or activated Factor IX and/or activated Factor XII, and/or activated Factor VII and/or activated Factor X in a sample capable of being administered to humans.
摘要:
Mutants of the DNA sequence coding for the protease (FSAP) which activates blood clotting factor VII and single-chain plasminogen activators, the mutants comprising a G/C base exchange at nucleotide position 1177 and/or a G/A base exchange at nucleotide position 1601, are described. The corresponding protease has a Glu/Gln exchange at amino acid position 393 and/or a Gly/Glu exchange at amino acid position 534. Diagnostic methods which are used for detecting FSAP in body fluids or tissue cells and also for identifying patients with genetic heterozygous or homozygous FSAP expression are also described. In addition, antibodies against FSAP and its mutants are disclosed and diagnostic methods which can be used to detect antibodies against FSAP and its mutants are specified.
摘要:
The present invention relates to the use of coagulation proteins and complexes thereof with anticoagulation proteins for the lysis of blood clots or other applications affected by accelerated plasmin production. More specifically, the present invention provides a method for accelerating the dissolution of a blood clot through the administration of at least one coagulation protein, with or without being in complex with a serpin, comprising a basic C-terminal amino acid, wherein the coagulation protein may be a derivative of Factor X or Factor V or a combination thereof. Pharmaceutical compositions for the treatment and prophylaxis of blood clots are also provided, wherein, the methods and products of the present invention advantageously accelerate clot dissolution while potentially minimizing the adverse side-effects, such as hemorrhaging, seen with other clot dissolving agents. The present invention also provides a method for detecting a fibrinolytic potential in a subject.
