Product details

Thrombin Inhibitor Screening Assay Kit (Fluorometric) (ab197007) is an assay where the synthetic AMC-based peptide substrate provided is proteolytically cleaved by Thrombin in order to release a fluorophore, AMC, which can be easily quantified by fluorescence reader at Ex/Em = 350/450 nm. In the presence of Thrombin specific inhibitors, the extent of cleavage reaction is reduced or completely abolished. The loss in the fluorescence intensity can be correlated to the amount of inhibitor present in the assay solution.

The kit provides a simple and rapid method to screen potential inhibitors of thrombin and to characterize thrombin inhibitors found in plasma samples.

This product is manufactured by BioVision, an Abcam company and was previously called K374 Thrombin Inhibitor Screening Kit (Fluorometric). K374-100 is the same size as the 100 test size of ab197007.

Thrombin enzyme (Factor IIa) is an important clotting factor that controls the transformation of soluble fibrinogen to insoluble active fibrin strands. Thrombin is a serine protease (EC 3.4.21.5) that catalyzes many coagulation-related reactions. Thrombin inhibitors are used as anticoagulants to prevent arterial and venous thrombosis. Some of these inhibitors are currently in clinical use while others are in clinical development.

Supplementary information

Thrombin also known as Factor II or thrombin protein is a 36 kDa serine protease essential for blood coagulation. It is produced in the liver as prothrombin and activated in the coagulation cascade. Its expression occurs extensively in the liver where it plays an important role in converting soluble fibrinogen into insoluble fibrin forming blood clots. Thrombin also activates various other coagulation factors including Factors V VIII and XI amplifying the coagulation response. Biotinylated thrombin variations help in detection and research applications.
Biological function summary

Thrombin modulates several physiological processes beyond clot formation. It serves as a signaling molecule interacting with protease-activated receptors (PARs) to influence cell functions including proliferation migration and apoptosis. Thrombin forms part of the prothrombinase complex comprised of prothrombin activated Factor X (Xa) and Factor V on phospholipid surfaces. This complex is critical for thrombin generation during the clotting cascade. Thrombin's activity extends to involvement in wound healing and inflammation regulation.

Pathways

Thrombin significantly participates in the coagulation and fibrinolytic pathways. It not only converts fibrinogen to fibrin in the coagulation pathway but also activates inhibitors like antithrombin which regulates thrombin and other protease activities. Thrombin's interaction with fibrinolysis where tPA and plasminogen are substrates integrates clot disintegration processes. Thrombin's connectivity with proteins such as Factor VII Protein C and antithrombin outlines its diverse role in maintaining hemostatic balance.

Thrombin associates with conditions such as venous thromboembolism and disseminated intravascular coagulation (DIC). Dysregulation of thrombin leads to excessive clotting contributing to thromboembolic diseases. In DIC uncontrolled thrombin activity results in systemic coagulation consuming clotting factors and increasing bleeding risk. Its function alongside proteins like Factor V Leiden and antithrombin deficiencies aggravate thrombotic conditions. Research into thrombin inhibitors aids in developing therapeutic strategies for these disorders.

Target data

Thrombin, which cleaves bonds after Arg and Lys, converts fibrinogen to fibrin and activates factors V, VII, VIII, XIII, and, in complex with thrombomodulin, protein C. Functions in blood homeostasis, inflammation and wound healing. Activates coagulation factor XI (F11); activation is promoted by the contact with negatively charged surfaces (PubMed : 2019570, PubMed : 21976677). Triggers the production of pro-inflammatory cytokines, such as MCP-1/CCL2 and IL8/CXCL8, in endothelial cells (PubMed : 30568593, PubMed : 9780208).
