I have been doing ChIPs for a very long time and have tried many kits from different sources like Active Motif, Millipore/Upstate, and homemade reagents. The reproducibility and binding efficacy were never optimal for these until a colleague recommended the iDeal ChIP-seq Kit for Transcription Factors from Diagenode. I have done more than one hundred samples of ChIPs and ChIP-seq using this kit. The results are very consistent and the binding efficacy is higher than with all the other methods. I would definitely recommend this ChIP kit from Diagenode to anyone who is trying to do ChIP or ChIP-seq.

The system performance was very good. High molecular weight DNA of different plants (Arabidopsis Alm, Hops polaris and wine Villard Blanc) was isolated and diluted to 50ng/µl or 70ng/µl. We aimed for fragment length 30kb at the volume 150µl.
We achieved good results and we will continue with bead purification and library preps for PacBio sequencing.  I like the user friendly interface of the Megaruptor® 2. Just two parameters had to be specified: volume of each sample and desired mean fragment size. The processed DNA has a narrow size distribution at around 30kb.

about Megaruptor® 2.

At the VIB Department of Molecular Genetics we strive to implement the best technologies in our workflows. Recent advances in long read sequencing using Oxford Nanopore technology have made the investigation of complex genomic variation in the human genome possible. A crucial step in the beginning of the library preparation is the shearing of genomic DNA, and this is where we implement the Megaruptor. The straightforward protocol is efficient, requires minimal sample handling and results in very reproducible fragment sizes. Another advantage is the consumable cost, which is lower than alternative technologies. For our applications we prefer shearing to lengths of 10 to 40kb, and for this the Megaruptor is the optimal solution.

about Megaruptor®.

High throughput sequencing has dramatically reduced sequencing costs and the development of duel indexing strategies makes it possible to combine 384 samples in a single sequencing run. By developing library preparation methods to enrich for retroviral integration sites and retroviral transcripts we have been able to produce large numbers of low cost libraries to track the evolution of infection and to characterise patterns of expression from our virus of interest. The Bioruptor® Pico has been essential part of our protocols and provides straightforward and consistent shearing of our samples.

We use the Bioruptor sonication device and the antibody against the histone modification H3K4me3 in our lab. The Bioruptor device is used for the shearing of chromatin in ChIP-Seq experiments and for generation of protein lysates (whole cell extracts). Thanks to the Bioruptor device we achieve excellent and reproducible results in both applications. The H3K4me3 antibody is used in our ChIP-Seq experiments as well as Western Blotting. With this antibody we are able to generate highly enriched ChIP-Seq samples with extremely low background. In Western Blot we can detect one specific, strong band with the H3K4me3 antibody.

Diagenode provides not only very good products for research but also an excellent customer support.

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!

Our lab has used Diagenode’s Premium RRBS kit on rat brain samples. The protocol is understandable, logical, well-written and is easy to follow. It is a complicated, but ingenious kit. I found it fantastic that I could ask questions from the company, and their answers were really useful. We were able to construct a library, which we ran on BioAnalyzer, and the results looked very nice and ready to be sequenced. I would definitely recommend my colleagues to use the Premium RRBS kit from Diagenode.

The Norwegian sequencing centre (NSC) is a national core facility fully equipped to handle a diverse set of sequencing projects. We see an increased interest in long read technologies, in which our PacBio Single Molecule sequencing service is important. PacBio, (or SMRT) sequencing, like any other single molecule system, starts with a critical library preparation step to generate long fragment libraries of 10-20kb length. Even longer libraries can be made, but common to all library types is to start with good quality DNA of high molecular weight. Physical shearing of the DNA, targeting the desired library length, is the first critical step in the procedure. NSC has experience with different methods to fragment DNA like nebulization, enzymatic, tagmentation, covaris AFA, g-tubes (also covaris), custom syringe/needle protocols and hydroshearing. The best fragmentation method should produce a sharp fragmentation pattern close to the target length as defined by the protocol settings, with as little “smear like” pattern of lower molecular length as possible. The final step of PacBio library preparation is to size select only the longest fragments (> 7kb) as this increases the overall success rate of only sequencing the longest library fragments. It is not uncommon to loose a lot of material during this step. However, if the initial fragmentation yields sharp fragmentation patterns with minimal smear, more of the total DNA is retained in the final library. This is perhaps most important on samples were DNA amounts are limited. The optimal fragmentation method has to produce similar fragmentation pattern each time, with little deviation with sample type and input amount. We have found the new Megaruptor from Diagenode to be one of the best instruments for routine shearing of DNA to lengths of 2-40kb. It is easy to use, with walk away shearing, and the instrument does all the washes before, in between samples and after shearing without user intervention. Disposable hydropores is beneficial for lowering the contamination risk. The fact that it is so easy to use make it a good choice for laboratories with multiple users and/or when training new staff.
