General description

Thrombin is the final coagulation protease in regard to hemostasis, promoting both procoagulant and anticoagulant effects.

Application

Thrombin is used for site specific cleavage of recombinant fusion proteins containing an accessible thrombin recognition site for removal of affinity tags. Thrombin has been used in a study to investigate activation of equine platelet-rich plasma.
Thrombin is used for site specific cleavage of recombinant fusion proteins containing an accessible thrombin recognition site for removal of affinity tags.

Biochem/physiol Actions

Serine protease that selectively cleaves Arg-Gly bonds in fibrinogen to form fibrin and fibrinopeptides A and B.

Unit Definition

Activity is expressed in NIH units obtained by direct comparison to a NIH Thrombin Reference Standard, Lot K.

Physical form

Lyophilized from saline sodium citrate buffer, pH 6.5

Analysis Note

The NIH assay procedure uses 0.2 ml diluted plasma (1:1 with saline) as a substrate and 0.1 ml of thrombin sample (stabilized in a 1% buffered albumin solution) based on a modification of the method of Biggs. Only clotting times in the range of 15-25 seconds are used for determining thrombin concentrations.
