[Purification and activity calculated of fibrinolyric factors from Eupolyphaga sinensis]
1Bioengineering Department, Guangdong University of Technology, Guangzhou 510090, China.
Three kinds ( EFF-1, EFF-2 and EFF-3) of fibrinolytic factor were separated by ammonium sulphate precipitation, DEAE-cellulose and preparative PAGE electrophoresis from female Eupolyphaga sinensis Walker. Their molecular weights were proved to be 41kd, 32.9 kd and 30.6 kd respectively with SDS-PAGE electophoresis. Their Activities as plasminogen activator were 171.3 U/mg, 234.0 U/mg and 148.5 U/mg. In addition, EFF-2 and EFF-3 were not only fibrinolytic activities but also have plasminogen activator on fibrinous plate lacked of plasminogen . There had been no such components of plasminogen activator and fiberinolytic enzyme from Eupolyphaga sinensis reported yet.
