Output Units
Output Notes CNBs-siLINC00511 + US showed highest transfection (~86.7% FAM+ by flow cytometry) and increased apoptosis with cisplatin; ultrasound: 1 MHz, 1 kHz PRF, 50% duty, 1.0 W/cm2, 30 s; nanobubbles 3×10^8/mL.
Toxicity Notes Very low toxicity at 24 h post-transfection; proliferation inhibited at 48 h after transfection (reported).
