Factor X (FX) is a glycoprotein synthesized by the liver, dependent on vitamin K. FX is involved in the common pathway of coagulation.
It is activated in FXa by the FT-FVIIa complex or by the FVIIIa-FIXa complex in the presence of phospholipids.
FXa is neutralized by TFPI and antithrombin.
- Deficient plasma of human origin, stabilized and lyophilized with an activity < 1% of the corresponding coagulation factor. All other coagulation factors have normal values.
- Deficient plasma obtained by immunoadsorption.
- The FX-deficient plasma is used for the FX assay by the one-step method using thromboplastin.
Deficient plasma can be aliquoted and frozen for 1 month at -20 °C after reconstitution.
- 5 vials x 1 mL lyophilized plasma
