Coagulation Factor VIIa, Human Plasma
Native coagulation factor VIIa from human plasma prepared from human Factor VII using human Factor XIIa, which was removed after activation. In the coagulation process, after complexing with tissue factor and membrane phospholipids, Factor VIIa activates Factors IX and X to the enzymatically active Factors IXa and Xa. Provides a crossover point between the extrinsic and intrinsic pathways.
