FIELD: production methods.
SUBSTANCE: method is based on the capability of defibrotide to increase the fermentation activity of plasmin and foresee the stages: a) making the contact in reactional area defibrotide, plasmin and substrate specific for plasmin which, because of reaction, provides the defined product b) the definition of the amount of obtained product in temporary points.
EFFECT: invention allows to define the biological activity of defibrotide in comparison with standard etalon with height accuracy and big repeatability.
