which can be used for qualitative and semi-quantitative analysis. Several key factors were studied and discussed. The concentration of fibrinogen and plasminogen contained in the fibrin plate did not have any effect on the fibrinolytic area. However
the concentration of fibrinogen had influence on the observation and image gathering of fibrinolytic zones. It was difficult to clearly observe the fibrinolytic zones when the concentration of fibrinogen was below 02 mg/mL. The logarithm of the product of the two perpendicular diameters was linearly related to the logarithm of the concentration of urokinase when the concentration of urokinase was among 2~250 mU/μL. In the experiment
the optical concentration of urokinase was among 10~20 mU/μL. It is found that it is hard to denature plasmin by heating the agar-fibrin plate after the agar is solidified. However
the plasmin is completely denatured when heated at 95 ℃ for 40 minutes before the agar is solidified.
