General description

Lyophilized powder containing sucrose, sodium chloride and Tris.
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 assess an innovative flow cytometric approach for small-size platelet microparticles.

Biochem/physiol Actions

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

Unit Definition

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

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.

Microparticles (MPs) are small submicron membrane-derived vesicles shed from a variety of cells and they have been implicated in different disorders. Accordingly, understanding of physiological characteristics of MPs and improvement of methods of their quantification are important for further advance
