Follow our guidelines and find the good parameters for your expected DNA size: DNA shearing with the Bioruptor® Pico

Neonatal screening cards provide a valuable bio-bank for retrospective studies. We have used the Bioruptor Pico and IP-Star Compact instrument along with the Auto MeDIP and IPure v2 kit to generate genome-wide DNA methylation profiles using only minute DNA inputs. Using the Diagenode instruments and products has generated reproducible results and saved us hands-on time. We are satisfied with the level of service and technical support and would recommend Diagenode to all others working in the field of epigenetics.

I work with Diagenode’s Plant ChIP-seq kit and shear the DNA on the Bioruptor Pico for the last year and I have to say that these two products saved my PhD project! Some time ago, our well-established ChIP protocol suddenly stopped to work and after long time of figuring out the reason, we invested into Bioruptor Pico. I am very satisfied from the way it works, plus it’s super quiet! Combining the sonicator with the Plant ChIP-seq kit we finally got things working. I have also decided to try the Microplex Library Prep kit, which is amazing. I have been working with other kits and I find this one efficient and very easy to use. Recently, I have tested one of the epigenetics antibody (H3K4me3) and it works very well on the plant tissue, together with the ChIP-seq kit and Bioruptor.

Thanks Diagenode for saving my PhD!

I have extensively used the antibodies against the histone modifications H3K4me3, H3k27me3, H3K9ac, H4k8ac and H3K18ac provided by Diagenode. The high level of specificity and selectivity of these antibodies in mouse brain samples, confirmed by using several negative and positive controls run in parallel with mouse brain tissue samples, ensured successful and reproducible results. I have been a Diagenode costumer for over one year now and I am extremely satisfied with the efficiency of the Bioruptor Pico for chromatin shearing as well as all of the ChIP materials (i.e., antibodies, blocking peptides, primer pairs for qPCR) provided by this company. Many thanks.

We are particularly satisfied with the Bioruptor^® Pico that we have recently purchased. Since we have started using this novel machine, all experiments for our epignetics research have been much more easy to perform. This machine is really a great thing for us. The whole department has now started using this novel device.

Diagenode has provided a Bioruptor^® Pico demo instrument to us for 2 weeks in September. We were getting very reproducible results between different tubes in the same sonication as well as between replicate experiments. We have obtained considerably improved results especially  for cross-linked chromatin from mammalian cells that has always been a problem for us with the old Bioruptor. A bonus also was a reduced sonication time, although the preparation time is slightly delayed due to the glutinous nature of the beads.

The new Bioruptor^® Pico machine has reduced the amount of time spent sonicating Chromatin by a massive amount. Some protocols require quite harsh fixing conditions which meant fragmenting DNA on the old machine was taking many rounds and several times. With the new Bioruptor^® Pico machine these sonications were taking just one round of 10 cycles thereby reducing the fragmentation time substantially. Following sonication, I have used the new IDeal ChIP-seq kit. This is a nice straight forward kit that if followed with an appropriate chip validated antibody gave amazing chip-seq results that worked time and again with several different transcription factors. I would recommend both kits for good, consistant chromatin work.

The Bioruptor® NGS* is a robust user-friendly sonication system that is key for both reproducible chromatin shearing and DNA shearing. The Bioruptor® NGS consistently delivered optimal DNA shearing that was critical in generating homogeneous sequencing libraries for our experiments. We also observed excellent chromatin shearing result that were crucial for our epigenetic mapping projects.

It is important to establish optimal conditions to shear crosslinked chromatin to get the correct fragment sizes needed for ChIP. Usually this process requires both optimizing sonication conditions as well as optimizing SDS concentration, which is laborious. With the Chromatin Shearing Optimization Kits, optimization is fast and easy - we provide optimization reagents with varying concentrations of SDS. Moreover, our Chromatin Shearing Optimization Kits can be used for the optimization of chromatin preparation with our kits for ChIP.
