A method for the determination of soluble fibrin in a body fluid of a species is described, entailing use of a binding partner which is bound to a solid phase, and of a labeled bioaffinity binding partner, for fibrin.

Method for the determination of 'soluble' fibrin

The present invention provides a method for the determination of a component of an immune reaction in a plasma sample using an immunoassay at a temperature of from 15.degree. to 40.degree. C., where one of the reactive components is in solid phase. The invention involves adding an amount of plasminogen activator sufficient to eliminate interference by fibrinogen with the component to be determined.

Process for the determination of a component of an immune reaction in a

The present invention provides a dry reagent for blood coagulation tests in which an at least partial course of the coagulation cascade takes place, comprising a carrier material which contains a chromophoric substrate of a protease of the blood coagulation system, at least one factor and/or co-factor of the blood coagulation system and a buffer.

Dry reagent for blood coagulation tests

A process for the preparation of a factor VIII:C-deficient plasma is made available, in which a starting plasma is consecutively treated with antibodies against von Willebrand factor and antibodies against factor VIII:Ag. The deficient plasma prepared in this way contains less than 0.5% residual activity of factor VIII:C.

Process for the preparation of factor VIII:C-deficient plasma, and a

The present invention provides a process for the simultaneous determination of fibrinogen and fibrinogen fission products in plasma, wherein 0.01 to 1 U of a snake venom enzyme with a thrombin-like effectiveness is aded per ml. of sample plasma, then there is measured the period of time between the addition of the enzyme and the commencement of a turbidity formation as a measure for the amount of fibrinogen fission products and subsequently there is measured the speed of the turbidity formation as a measure of the amount of fibrinogen. The present invention also provides a reagent for the simultaneous determination of fibrinogen and fibrinogen fission products, wherein it comprises 0.01 to 10 U snake venon enzyme with thrombin-like effectiveness per ml. of sample plasma, 0.5 to 4% by weight of a water-soluble polyalcohol, 1 to 20 mMole/liter of calcium ions and 0.05 to 0.3 mole/liter of buffer of pH 7.0 to 8.0, referred to the solution ready for use, as well as optionally a detergent.

An agent for determining ristocetin cofactor (v.Willebrand factor) is described, which contains platelets which have been treated with a tanning agent, with a protease inhibitor and, optionally, with a dye-stuff, and ristocetin A.

Reagent for the determination of ristocetin cofactor (v.Willebrand

The present invention provides a reagent for the optical determination of blood coagulation behavior (Quick test), comprising thromboplastin, a synthetic thrombin substrate and a buffer, characterized by a content of non-proteolytically active thromboplastin.

Reagent for the optical determination of the blood coagulation

The present invention provides a process for the detection or determination of fibrin monomer in biological fluids, wherein the sample fluid is incubated with hydrophobic latex and the agglutination determined. The present invention also provides a reagent for the detection or determination of fibrin or fibrin monomer in biological fluids, wherein it contains hydrophobic latex.

Method and reagent for the detection of fibrin monomer

A tissue thromboplastin preparation which is sensitive to coagulation factor VII, is prepared from acetone dry powder mammalian tissue, by extraction with a salt solution containing 1 to 20 mmol/1 of calcium ions and, if desired, a surface active agent, after which the extract maybe dried.

Method of preparing tissue thromboplastin

Process for the manufacture of a collagen solution and its use for the manufacture of collagen fibrillae for adsorbing coagulation factors, as diagnostic agent, for the manufacture of a collagen sponge and for use in a cosmetic preparation.
