We present an in vitro model which allows the study and analysis of coagulation in whole, non-anticoagulated blood. Anticoagulation in the system depends on the natural anticoagulation effect of healthy endothelial cells and endothelial cell activation will result in clotting.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

2024
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban. Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Rapid Point-of-Care Assay of Enoxaparin Anticoagulant Efficacy in Whole Blood

2012
Demonstration of a rapid quantitative assay of the inhibition of blood coagulation by the low-molecular-weight-heparin, enoxaparin. The contribution of enoxaparin is assessed by removing its influence through digestion with heparinase. A fuller description of the assay is detailed in our published paper.1 The assay still requires clinical confirmation.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

A simplified yet accurate method to collect and stain mosquito hemocytes is described. Our method combines the simplicity of perfusion with the accuracy of high injection techniques to isolate clean preparations of hemocytes in Aedes mosquitoes. This method facilitates studies requiring knowledge of the types of hemocytes and their abundance.

Its anticoagulant component acts by either binding calcium or inhibiting clotting, depending on the reagent. By interrupting coagulation, the liquid keeps the sample in a usable state while its diluent portion establishes the concentration needed for counting or assay preparation. This dual action helps prevent clotting during handling and supports more consistent laboratory analysis.
Small changes in ionic strength, cell concentration, or clotting status can shift assay performance. Ionic strength describes the chemical environment created by dissolved substances, while cell concentration affects measurements based on counts or sample composition. If these variables differ between preparations, results may become difficult to compare, even when the underlying biological samples are similar.
The prepared liquid helps maintain both cellular and soluble components while samples are handled. Preserving these components supports measurements involving leukocytes, immune cells, and soluble targets in blood-based assays. Maintaining the sample in a controlled medium is especially relevant when subsequent analysis depends on cell counts, sample composition, or interactions measured in serological and cellular tests.
A basic workflow uses the prepared liquid as a controlled medium for mixing, concentration adjustment, counting, or assay preparation. The sample and diluent must retain a consistent composition and dilution so that clotting status and cell concentration remain suitable for the intended analysis. This standardization helps laboratories compare measurements across samples rather than changes caused by preparation.
It is useful when researchers need to process whole blood or prepare samples for leukocyte and immune-cell measurements. The same approach can support pathogen detection as well as serological and cellular assays. Its value comes from maintaining analyzable cellular and soluble components while controlling sample concentration, allowing different types of immunological or infection-related measurements to be performed consistently.
Inconsistent dilution can change the concentration of cells or soluble components presented to an assay, while incomplete control of clotting can alter the sample state. These effects may influence counting, pathogen detection, serological results, or cellular measurements. Consistent preparation therefore improves comparisons between samples and helps distinguish biological differences from variation introduced during laboratory handling.
