In vitro Rt-PA delivery in the full occlusion model. Blood clots were treated with a range of Rt-PA alone in a range of concentrations (0, 3, 30 µg/ml). The blood clot volume was assessed every 5 min for 60 min using high frequency ultrasound imaging. 3D reconstructions of clots were made at T0 and T60 (top). I-J: Control; K-L: Rt-PA; M-N: Rt-PAx10. Data expressed as mean ± SEM were calculated from four independent experiments (bottom).
