Bovine Activated Protein C

BPCa                         Bovine Activated Protein C

Activated Protein C （APC） is a serine protease derived from the two chain vitamin K dependent zymogen, Protein C. APC inhibits blood coagulation through the selective inactivation of the cofactors Va and VIIIa. APC is prepared from protein C by activation with purified thrombin. This thrombin is removed after activation by ion exchange chromatography. Activated Protein C purity is determined by SDS-PAGE and shows complete reduction upon incubation with 2-mercaptoethanol.

Buffer composition = 20 mM Tris-HCl/0.1 M NaCl /pH 7.4
Extinction Coefficient （1%） = 13.7
Molecular Weight = 52,650 daltons
