General description
Thrombin enzyme (activated factor IIa) is an important clotting promoter that controls the transformation of soluble fibrinogen to insoluble active fibrin strands. Thrombin is a coagulation protein and a serine protease (EC 3.4.21.5) that catalyzes many coagulation-related reactions. It is primarily associated with blood clotting.
Biochem/physiol Actions
Thrombin triggers factor-XI, factor-V, Factor-XIII and factor-VIII. Thrombin endorses platelet activation, using activation of protease-activated receptors on the platelet. It also induces inflammation. As a result of its high proteolytic specificity, thrombin has become an important biochemical protein. The thrombin cleavage site (Leu-Val-Pro-Arg-Gly-Ser) is widely used in linker regions of recombinant fusion protein constructs. After the purification of the fusion protein, thrombin is used to cleave between the Arginine and Glycine residues of the cleavage site, efficiently removing the purification tag from the protein of interest with a high degree of specificity.
Physical form
Lyophilized from a buffer composed of 20 mM Bis-Tris, 150 mM NaCl and 0.1% PEG 8000, pH 6.5.
Reconstitution
A working stock solution can be prepared by adding 1 mL buffered saline, pH 7.4 (ex. 25 mM HEPES, 150 mM NaCl, 0.1% PEG 8000, pH 7.4). Further dilution should be made in buffer containing a suitable stabilizing agent such as 0.1%-1% Prionex, BSA, or PEG.

Cellular therapies remain constrained by the limited availability of sensors for disease markers. Here we present an integrated target-to-receptor pipeline for constructing a customizable advanced modular bispecific extracellular receptor (AMBER) that combines our generalized extracellular molecule sensor (GEMS) system with
