Conditions in which serum or tissue acrolein levels are high (e.g.: renal failure, heavy smoking, oxidative stress) are also associated with increased thrombogenicity. Another emerging cardiovascular risk factor is homocysteine, and its derivative, homocysteine thiolactone. Antithrombin is one of the

Biodegradable polymers have potential as a scaffold material for making small diameter artery bypass grafts. To resist thrombosis, maintain biocompatibility and enhance the remodeling of the grafts, it is crucial to modify polymer scaffolds so that the grafts have antithrombogenic

Coagulation balance is maintained through fine-tuned interactions among clotting factors, whose physiological concentrations vary substantially. In particular, the concentrations of coagulation proteases (pM to nM) are much lower than their natural inactivator antithrombin (AT, ~ 3 μM), suggesting the existence of other coordinators.

Protocols

Thrombin from Bovine Plasma

Thrombin is an endolytic serine protease that selectively cleaves the Arg–Gly bonds of fibrinogen to form fibrin and release fibrinopeptides A and B.
