The F2 gene encodes thrombin protein and is mapped to human chromosome 11p11.2.
Application
Thrombin from human plasma has been:
- dissolved in CaCl2 and added to poly ethylene glycolated fibrinogen/cell solution for fibrin production
- to polymerize fibrin on well plates
- used as an endogenous agonist proteinase for proteinase-activated receptors : PAR1, PAR3 and PAR4 for stimulation of cells
Biochem/physiol Actions
Serine protease that selectively cleaves Arg-Gly bonds in fibrinogen to form fibrin and fibrinopeptides A and B.
Thrombin is an endolytic serine protease which stimulates vascular damage induced-leukocytes, platelets, endothelial and mesenchymal cell production. This action is mediated via G-protein-coupled receptor. It catalysis the cleavage of fibrinogen at Arg−Gly bonds to form fibrin and release fibrinopeptides A and B. The predominant form of thrombin in vivo is the zymogen prothrombin (factor II), which is produced in the liver. Prothrombin is a coagulation activation factor, high levels of which indicates cancer. Thrombin can be used to cleave fusion proteins. Cleavage of fusion proteins can be carried out at a thrombin:fusion protein ratio of 1:500.
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 0.1ml 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

Hello! How long can we store the lyophilised powder in stock solutions at -20°C?
1 answer-
Stability of thrombin in solution is not evaluated. However, external reports have shown a 10% loss of activity per year when reconstituted at a concentration of 1mg/mL and stored at -20C. Freeze/thaw cycles should be avoided.

Which volume of liquid do I have to add to a 100 U T7009 vial? And T6884 vial? With which kind of liquid should the powder be dissolved?
1 answer-
The product is soluble in water (10 mg/mL). Stock solutions can also be prepared at a concentration of 100 units/mL in a 0.1% (w/v) BSA solution. Stock solutions remain active for one week at 0–5 °C. Solutions are most stable at pH 6.5, as a pH >7 will greatly reduce thrombin activity. Since thrombin solutions adsorb to glass, it is recommended to aliquot the solutions in plastic tubes and store at –20 °C for long-term storage. We can calculate the weight in MG for this lot of 250 UN product using lot specific information found on a CoA (Refer to a certificate).
For T7009-250UN for example: As per one lot in one CoA, units/mg is 1742.
1742 units = 1 mg
250 units = 1mg/1742 x 250 = 0.1435 mg
So, 250 units of this product lot contains 0.1435 mg (143.5 ug) of powder in vial.Helpful?

What is the cross reactivity of Thrombin?
1 answer-
Thrombin from any vertebrate species will clot the fibrinogen of virtually any other species. Fibrinogen from any mammalian source will cross-react with thrombin from any mammalian source, but it is not well known how thrombin and fibrinogen from different animals differ in their sequence. When any mammalian thrombin is injected into a different mammal, clotting will occur.
