Product details:
Thrombin Activity Assay Kit (Fluorometric) (ab197006) is simple, rapid and can detect Thrombin activity as low as 1 ng in samples.
In the thrombin activity assay protocol, a synthetic AMC-based peptide substrate is proteolytically cleaved by thrombin to release a fluorophore, AMC, which can be easily quantified by fluorescence reader at Ex/Em = 350/450 nm.
Thrombin activity assay protocol summary:
- add standards and samples to wells
- add reaction mix
- analyze with a microplate reader for 30-60 min
Other Notes
This product is manufactured by BioVision, an Abcam company and was previously called K373 Thrombin Activity Fluorometric Assay Kit. K373-100 is the same size as the 100 test size of ab197006.
Thrombin enzyme (Factor IIa, EC 3.4.21.5), a serine protease, is an important clotting factor in the coagulation cascade that involves the conversion of soluble fibrinogen to insoluble active fibrin strands.

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.
