Updated project metadata. We collected protoescoleces (PSCs) from individual bovine cysts. Then we incubated 20 uL of PSCs in RPMI medium supplemented with 10% fetal bovine serum with 2.5 mM hydrogen peroxide (treated) or without hydrogen peroxide (Control) for 2 h at 37 °C. After that we collected PSCs by sedimentatios in 1.5 mL tube and washed 4 times with PBS at 37°C.
