The Diagenode TDG recombinant protein (Cat. No. C23020101) is a very good tool. I used it as positive control in western blot analysis and during TDG ELISA activity assays. The protein is really active! Indeed the TDG recombinant protein perfectly works in glycosylase activity assays using marked oligos.Dr Francesco Spallotta, Division of Cardiovascular Epigenetics, Goethe University, Frankfurt am Main, Germany

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.

I have been a Diagenode customer for over two years now. I have used the antibodies against the histone modifications H3K4me3, H3K4me2, H3K4me1, H3k27me3, H3K9ac, H3K27ac etc. provided by Diagenode to perform western blots.The high level of specificity of these antibodies in Pristionchus pacificus samples, confirmed by using several negative and positive controls run in parallel with synchronized culture samples, ensured successful and reproducible results.
Also, I am satisfied with the service and the support of personnel of Diagenode. They are prompt in replying to my emails and very helpful with their advice. Thanks a lot!Vahan Serobyan, Prof. Dr Ralf J. Sommer's Lab, Max Planck Institute for Developmental Biology, Tübingen, Germany
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.

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.Borbála Vető, Institute of Enzymology, Budapest, Hungary

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.
I am working with Diagenode's antibodies for over 5 years now.

To expedite the larger-scale phenotyping of pollen number difference within Arabidopsis family, we have modified an existing method more suitable for our purpose of pollen counting using a Bioruptor®. We grew four plants per genotype. Three flower buds per plant were harvested and dried at 65°C overnight. We collected flower buds with mature pollen, but before the anthers were opened (flower stage 13). We did not use the first and second flowers of the inflorescence, as they tend to show developmentally immature flower morphologies. 30 μl of 5% Tween-20 is added to the dried flower and samples are sonicated using the Bioruptor® Plus with high power mode for 10 cycles (sonication cycle: 30 sec ON, 30 sec OFF) to separate pollen grains from the anthers. Then, all pollen solutions are measured with a cell counter.Misako Yamazaki, Evolutionary and Ecological Genomics (Kentaro Shimizu group), Institute of Evolutionary Biology and Environmental Studies, University of Zurich, Switzerland

about Picoruptor ® Sonicator.
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.Dr. Tatyana Nesterova, Department of Biochemistry, University of Oxford
about Picoruptor ® Sonicator, 15 ml Picoruptor Tubes & sonication 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.Dr. Karen Dawson, RNA Biology Group, Cancer Research UK Manchester Institute at the University of Manchester

We used the MicroPlex version 2 kit to generate libraries using ChIP DNA for several transcription factors and compared the results to a standard library generation protocol starting from 5ng of ChIP DNA. Even when we reduced the starting amount of DNA by 10-fold, the MicroPlex Kit produced the same high yields and quality of the libraries. As expected, the number of duplicate reads increased but 15 to 20 million unique reads were sufficient to achieve excellent enrichment data. We found that no information was lost, and the MicroPlex Kit helped produce data that was consistent with the standard protocol despite the lower input. On top of this, the MicroPlex Kit was extremely user-friendly and saved us time. The MicroPlex version 2 kit will make challenging ChIP-seq experiments that rely on very limited amount of starting material much easier with robust results.Katia Basso, PhD, Assistant Professor, Columbia University, New York
