  • Chromatin analysis
    Shear chromatin to the exact fragment size range needed for downstream ChIP-seq and ChIP-qPCR.

    The most important steps for a successful ChIP include both cell fixation and lysis, and chromatin shearing. Diagenode’s Bioruptor uses state-of-the-art ultrasound technology to give the highest chromatin quality for high IP efficiency and sensitivity for ChIP experiments with gentle yet highly effective shearing forces. Additionally, the Bioruptor provides a precisely controlled temperature environment that preserves chromatin from heat degradation such that protein-DNA complexes are wellpreserved for sensitive, unbiased, and accurate ChIP.

    Diagenode’s Bioruptor is the instrument of choice for chromatin shearing used for a number of downstream applications such as qPCR and ChIP-seq that require optimally sheared, unbiased chromatin

    Panel A, 10 µl volume: Chromatin samples are sheared for 10, 20 and 30 cycles of 30 sec ON/30 sec OFF with the Bioruptor Pico using 0.1 ml Bioruptor Microtubes (Cat. No. B01200041). Panel B, 100 µl volume: Chromatin samples are sheared for 10 cycles of 30 sec ON/30 sec OFF with the Bioruptor Pico using 0.65 ml Bioruptor Microtubes (Cat. No. WA-005-0500). Panel C, 300 µl volume: Chromatin samples are sheared for 5, 10 and 15 cycles of 30 sec ON/30 sec OFF with the Bioruptor Pico using using 1.5 ml Bioruptor microtubes (Cat. No. C30010016). Prior to de-crosslinking, samples are treated with RNase cocktail mixture at 37°C during 1 hour. The sheared chromatin is then de-crosslinked overnight and phenol/chloroform purified as described in the kit manual. 10 µl of DNA (equivalent of 500,000 cells) are analyzed on a 2% agarose gel (MW corresponds to the 100 bp DNA molecular weight marker).

  • Clinical applications
    Deparaffinize FFPE samples gently and completely without solvents

    FFPE nucleic acid extraction

    Deparaffinization of FFPE samples is typically performed using a non-polar solvent, such as xylene, or a mineral oil-based method which can be time consuming and messy. Diagenode’s Bioruptor is a superior method for removing the paraffin and rehydrating FFPE tissues in just one solvent-free step followed by a mild crosslink reversal to preserve DNA and RNA integrity. Efficient de-paraffinization of FFPE sections by sonication with Bioruptor 10 µm sections were sonicated for 3 cycles (30 sec ON/OFF at RT) with the Bioruptor Pico. The paraffin has been emulsified and completely dissociated from the tissue section. Chromatin shearing The most important steps for a successful ChIP include both cell fixation and lysis, and chromatin shearing. Diagenode’s Bioruptor uses state-of-the-art ultrasound technology to give the highest chromatin quality for high IP efficiency and sensitivity for ChIP experiments with gentle yet highly effective shearing forces. Additionally, the Bioruptor provides a precisely controlled temperature environment that preserves chromatin from heat degradation such that protein-DNA complexes are wellpreserved for sensitive, unbiased, and accurate ChIP.

  • Next Generation Sequencing: DNA, RNA, and DNA methylation studies
    Shear DNA to the exact fragment size range needed for downstream library preparation -- down to 5 ul of volumes for low inputs!

    DNA shearing

    Next-Generation Sequencing (NGS) has revolutionized genomics and biology. One of the most critical aspects of optimal library preparation is the quality of the DNA to be sequenced. The DNA must first be effectively and consistently sheared into the appropriate fragment size (depending on the sequencing platform) to enable sensitive and reliable NGS results. The Bioruptor and the Megaruptor® provide superior sample yields, fragment size, and consistency, which are essential for Next-Generation Sequencing workflows.

Figure A shows different DNA size distributions of sheared genomic DNA produced by varying the duration of sonication. The different curves depict a specific Bioruptor® Pico run, optimized to produce specific mean sizes and size ranges for NGS. Figure B-D show the excellent reproducibility in DNA shearing compatible with NGS librairies from Illumina, IonTorrent and exom capture protocols from Agilent and Roche NimbleGen requirements. All DNA samples (100ng-4ug/50ul) were analysed on Fragment Analyzer™ (Advanced Analytical).

    RNA shearing

    RNA sequencing is a highly accurate and sensitive method to obtain unprecedented information about the transcriptome. The RNA must be fragmented to an appropriate size for sequencing prior to reverse transcription. The Bioruptor provides unbiased RNA shearing for best cDNA synthesis and ensures high quality Next-Generation Sequencing.

The 100 µl samples are sonicated 15 minutes at 45°C in the Bioruptor Plus with high power for rapid small scale production of bilayer -loaded liposomes.

How the Bioruptor technology works

The Bioruptor Pico and Plus utilize a sonication bath-based rotor. The walls of the sonication bath reflect the ultrasound waves in a random but reproducible pattern. The samples in the tube holder are rotated through the ultrasound field to expose each sample to the same level and intensity of energy to ensure shearing consistency. A unique cooling system providing isothermal processing and the gentle ultrasound preserve and retain the integrity of biological samples and ensure high sample recovery.

Cavitation energy, expressed as % of the maximum level, is measured with PPB Ultrasonic/Megasonic energy meter (lower panel).

    What are the effects of ultrasound on biological samples?

    High powered ultrasound waves can produce gaseous cavitation in liquids. Cavitation is the formation of small bubbles of dissolved gases or vapors due to the alteration of pressure in liquids. These bubbles are capable of resonance vibration and produce vigorous eddying or microstreaming. This mechanical stress has multiple effects on biological samples including; effective chromatin shearing, DNA & RNA shearing, cell lysis and tissue homogenization. When using a probe sonicator, the microstreaming phenomenon is limited to the vicinity of the probe which can generate high amounts of heat and release metal fragments. In contrast, the Bioruptor sonication bath is equally exposed to ultrasound energy allowing for the dissipation of heat and providing uniform absorption of energy. How does it work? Ultrasonic waves generated by the transducer produce longitudinal vibrations (alternating compression and rarefactions) in the water bath (see figure below). These pressure fluctuations create millions of microscopic bubbles (cavities) caused by the negative pressures generated by the rarefaction stage. As the cavities are exposed to the positive pressures, produced by the compression stage, they oscillate and expand to an unstable size (up to 100 microns diameter). Finally the cavities will implode generating pressure extremes and temperatures at the implosion sites. In addition, shock waves and eddies radiate outwardly from the site of cavity collapse. The localized hot spots that last for microseconds can have temperatures of ~5,000ºC, pressures of ~500 atmospheres as well as heating and cooling rates >109 K/s. The cumulative energy generated by this cavitation phenomenon is extremely high and produces intense shearing forces (Figure 1).
