General description

The F2 gene encodes thrombin protein and is mapped to human chromosome 11p11.2.[1]

Application

Thrombin from human plasma has been:
  • dissolved in CaCl2 and added to poly ethylene glycolated fibrinogen/cell solution for fibrin production[2]
  • to polymerize fibrin on well plates[3]
  • used as an endogenous agonist proteinase for proteinase-activated receptors : PAR1, PAR3 and PAR4 for stimulation of cells[4]

Biochem/physiol Actions

Thrombin is an endolytic serine protease[5] which stimulates vascular damage induced-leukocytes, platelets, endothelial and mesenchymal cell production. This action is mediated via G-protein-coupled receptor.[6] It catalysis the cleavage of fibrinogen at Arg−Gly bonds to form fibrin and release fibrinopeptides A and B.[5] 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.[5] 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.[7]
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

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.

Questions

1–8 of 8 Questions  

  1. How much is 100UN of thrombin(T6884)? what is the weight in mg?

    1 answer

    1. Both of these Thrombin products - T7009 and T6884 - are sold by activity or units. The amount of powder in the vial is lot specific and based on the activity reported in the Certificate of Analysis.

      T6884-100UN, lot SLCP0517 tested at 2736 uits per milligram. The 100UN vial contains 36ug of powder per vial. See the link below to review this Certificate of Analysis:
      https://www.sigmaaldrich.com/certificates/sapfs/PROD/sap/certificate_pdfs/COFA/Q14/T6884-100UNSLCP0517.pdf

      T7009-100UN, lot SLCN9908 tested at 1742 units per milligram. The 100UN vial contains 57ug of powder per vial. See the link below to review this Certificate of Analysis:
      https://www.sigmaaldrich.com/certificates/sapfs/PROD/sap/certificate_pdfs/COFA/Q14/T7009-250UNSLCN9908.pdf

  2. How much does the T-7009-100UN weigh with and without packaging? Country of origin Germany?

    1 answer

    1. This product is packaged in units, the exact amount of product will depend on the lot-specific activity. For example, the SLCN9908 has a specific activity of 1742 units/ mg protein. The end user will receive 0.06 mg. The net weight of packaging is 1,000 mg. The product is manufactured in the USA.

  5. For thrombin, how do NIH units compare to International Units (IU)?

    1 answer

    1. One NIH unit of thrombin is equivalent to approximately 1.8 International Unit (IU) of thrombin.

      Helpful?

  6. What is the solution stability of Product T7009, Thrombin from human plasma?

    1 answer

    1. By analogy to thrombin from bovine plasma (T4648), we expect stock solutions of thrombin from human plasma to be stable for one week kept refrigerated at 2-8° C. Since thrombin solutions adsorb to glass, it is recommended to aliquot the solutions in plastic tubes and store frozen at -20°C or colder for long term storage.

      Helpful?

  7. What is the solubility of Product T7009, Thrombin from human plasma?

    1 answer

    1. Thrombin from human plasma gave a clear very faint yellow solution when dissolved at 100 unit vial plus 1 ml of 28 mM sodium barbital, 0.125M sodium chloride, 1% BSA, 0.5% PEG, pH 7.35.  Thrombin from bovine plasma (T4648) is soluble in water at 10 mg/mL.

      Helpful?

  8. What is the cross reactivity of Thrombin?

    1 answer

    1. 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.
