Abstract: THE METHOD OF THROMBOLYTIC RADIOASSAY IN VITROYang Yi① Niu Huisheng② Li Huaifen② Zhao Zhuanyou① Wang Yinlan② Liu Houxiao①(①Tianjin Institute of Pharmaceutical Research, State Pharmaceutical Administration of China, Tianjin 300193)(②Chinese Academy of Medical Sciences, Institute of Radiation Medicine, Tianjin 300192)ABSTRACTThe similar nature thrombus is made of 125Ifibrinogen with plateletrich or antithrombotic blood to culture together with plateletrich plasma and thrombolytic agent. The thrombolytic rate is calculated depending on the radioactivity of plasma. At the same time, some relative factors with thrombus and thrombolytic effects of recombinant stephylokinase (STAR) is discussed. These results show that radioassay technology is sensitive, stable, specific and wonderful method.Key words thrombodisease thrombolytic agent radioassay
