Human Prekallikrein congenital Deficient Plasma

These native coagulation factor-deficient plasmas are recommended for the evaluation of the activity of coagulation factors by the method of assaying the level of prothrombin (PT) or activated partial thromboplastin time (TCA) requiring the use of a plasma lacking in factor (<1%) in hemostasis.

- None of these plasmas contain inhibitors.
- No additives or preservatives.
- Freezing the plasmas makes it possible to keep the matrix perfectly intact and to avoid reconstitution.
- Packaging in plastic cryotubes suitable for all STA-R type micro-cup supports.

Prekallikrein is a glycoprotein, a serine protease zymogen. Non-covalently complexed with high molecular weight kininogen.
Prekallikrein participates in the activation of coagulation, fibrinolysis, the generation of kinins and inflammatory phenomena. It is activated into kallikrein by FXIIa.
