General description

Thrombin is a Na+ activated allosteric serine protease. It belongs to chymotrypsin family.[1] Thrombin is made of two polypeptide chains of 36 (A chain) and 259 (B chain) residues that are covalently attached with a disulfide bond.[1]
Thrombin is a coagulation factor IIa.[2] It is a serine endopeptidase that hydrolyzes peptide and ester bonds specifically at the carboxylic side of Arg.[3] The enzyme converts fibrinogen to fibrin.[4] The product contains EDTA and additional stabilizing agents.

Application

Thrombin has been used in the expression and purification of recombinant RELM (resistin-like moleculefamily members.[5] It has also been used in platelet spreading on fibrinogen[6][7] and immunostaining.[8]
Thrombin is used in coagulation research, medical research, protein-structure analysis, and biochemical research. It has been used for the stimulation of the platelets.[8][9]

Biochem/physiol Actions

Thrombin plays an important role in blood coagulation. It serve as a procoagulant factor while transforming fibrinogen into an insoluble fibrin clot. Thrombin can act as anticoagulant by the activation of protein C.[1]

Physical form

Lyophilizate

Preparation Note

Storage conditions (working solution): -15 to -25°C

Inhibitors: DFP, TLCK, PMSF, benzamidine, α1-antitrypsin, α2-macroglobulin, antithrombin III heparin, hirudin, and APMSF

Reconstitution

The reconstituted solution contains 20 mM EDTA.
Important note:
Use plastic vials and pipettes because thrombin will be adsorbed to glass surfaces!

Fibrinogen molecules are comprised of two sets of disulfide-bridged Aalpha-, Bbeta-, and gamma-chains. Each molecule contains two outer D domains connected to a central E domain by a coiled-coil segment. Fibrin is formed after thrombin cleavage of fibrinopeptide A (FPA)
