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 assess an expression and purification system for the biosynthesis of adenosine receptor peptides for biophysical and structural characterization.
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, and is measured by direct comparison to an NIH thrombin reference standard.
Reconstitution
When reconstituted with 1 mL water, vial contains stated activity in 0.15 M sodium chloride and 0.05 M sodium citrate, pH 6.5.
Analysis Note
Activity is expressed in NIH units obtained by direct comparison to a NIH Thrombin Reference Standard, Lot K.
The NIH assay procedure uses 0.2 mL of 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.

Biophysical and structural characterization of G protein-coupled receptors (GPCRs) has been limited due to difficulties in expression, purification, and vitro stability of the full-length receptors. "Divide and conquer" approaches aimed at the NMR characterization of peptides corresponding to specific regions

Platelet-rich plasma (PRP) is typically isolated and applied immediately after preparation, making it both a time- and labor-intensive addition to the operative procedure. Thus, it would be convenient if PRP could be preserved. We evaluated the efficacy of freeze-dried PRP

Polymer nanoparticles (NPs), due to their small size and surface functionalization potential have demonstrated effective drug transport across the blood-brain-barrier (BBB). Currently, the lack of in vitro BBB models that closely recapitulate complex human brain microenvironments contributes to high failure
