*Cells that were centrifuged down and transferred to tubes were sonacated for 30 seconds and not for 30secounds. This process was repeated three times for each test tube of cells. | *Cells that were centrifuged down and transferred to tubes were sonacated for 30 seconds and not for 30secounds.

* In principle, the high-frequency is generated electronically and the mechanical energy is transmitted to the sample via a metal probe that oscillates with high frequency. The probe is placed into the cell-containing sample and the high-frequency oscillation causes a localized low pressure region resulting in cavitation and impaction, ultimately breaking open the cells. Although the basic technology was developed over 50 years ago, newer systems permit cell disruption in smaller samples (including multiple samples under 200 µL in microplate wells) and with an increased ability to control ultrasonication parameters (wikipedia.com). | * In principle, the high-frequency is generated electronically and the mechanical energy is transmitted to the sample via a metal probe that oscillates with high frequency.
