This, fully active, wild-type human alpha thrombin protein was expressed recombinantly in E. Coli and purified to >95% (by SDS-PAGE).
Thrombin is a serine protease that possesses trypsin-like behavior in that it prefers to cleave its substrates after arginine and lysine residues. It elicits functional responses critical to blood homeostasis by interacting with diverse physiological substrates.

|Purity:||>95% by SDS-PAGE|
|Buffer:||300mM NaCl, 20mM Tris pH 7.4|
|Activity:||Wild-type, active form. Activity is determined by using the very potent thrombin inhibitor hirudin to active site titrate the thrombin we prepared for Kerafast. Based on this titration, the material is 93% active. The uMolar active site titrated concentration is 2.91uM. If you consider the conversion of 1 NIH unit = 0.324ug of WT thrombin there are 287 units of WT thrombin in each 100ug vial. This value takes into account the 93% active site titration correction.|
