Általános leírás

Hirudin is a 7 kDa acidic protein containing 65 amino acid residues that has an isoelectric point of 3.5-4.0. It is not glycosylated and lacks tryptophan, arginine and methionine residues. It is chemically stable between pH 2-12 and at temperatures up to 80°C.

Biokémiai/fiziológiai hatások

The anticoagulant, hirudin, is the most potent natural inhibitor of both soluble and clot-bound thrombin. It forms a high-affinity 1:1 complex with thrombin, occluding both the proteolytic site and exosite I (fibrinogen and PAR recognition site). Hirudin blocks thrombus growth and platelet activation, and has been suggested as the clinically preferred anticoagulant (over heparin and citrate) for its specific mode of action and absence of side effects. It is not metabolized in the bloodstream of humans and is eliminated unchanged via kidney filtration.

Egység definíció

One unit (ATU) will neutralize one NIH unit of thrombin at 37 °C, based on direct comparison to an NIH thrombin reference standard.

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.
