Descripción

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 evaluate the in vitro effect of low molecular weight heparin on thrombin generation in cirrhotic patients at different stages of liver disease.

Biochem/physiol Actions

Serín proteasa que hidroliza selectivamente los enlaces Arg-Gly en el fibrinógeno para formar fibrina y fibrinopéptidos A y B.

Physical form

Lyophilized from 0.02 M Bis/Tris buffer, pH 6.5, 0.15 M NaCl and 0.1% PEG-8000

Analysis Note

The NIH assay procedure uses 0.2 ml diluted plasma (1:1 with saline) as a substrate and 0.1ml 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.

Other Notes

Activity is expressed in NIH units obtained by direct comparison to a NIH Thrombin Reference Standard
