Testimonials

We have had an excellent experience with the RRBS service provided by Diagenode. Our project was based on DNA extracted from human fresh and paraffin-embedded skeletal muscle, and the RRBS and Bioinformatic results were reliable and consistent with what we expécted. We highly recommend their service

about DNA Methylation Profiling (RRBS Service).

We are very happy with the services provided by Diagenode. In our project, Reduced Representation Bisulfite Sequencing (RRBS) was used and it worked well for both high-quality DNA and DNA extracted from formalin-fixed, paraffin-embedded (FFPE) material. Bioinformatic analyses were comprehensive and high-quality results were obtained. Diagenode’s services can be recommended.

about DNA Methylation Profiling (RRBS Service).

We sheared the DNA on the Diagenode One and used the MicroPlex Library Preparation v2 Kit to create DNA libraries for whole genome sequencing of four plant species for which there is no reference genome available. Previous attempts with a commercial Tn5-transposase based method gave unsatisfactory results. However, the Diagenode MicroPlex kit was quicker, easier, and gave the expected profile of fragment sizes. In just 30 seconds of sonication, we obtained a fragment distribution centered at 270 bp. The library construction took only 2 hours with this kit. The library was sequenced in a NexSeq 550 in High-Output mode, giving 85% based with>Q30.

I like the Diagenode CATS RNA-seq kit for a number of reasons. 
The kit is approachable for any research user. The things I care about are time, reproducibility, and ease. In my hands, the CATS mRNA-seq kit has generated highly reproducible libraries from very low input RNA that goes into polyA selection. This has significantly decreased the amount of time I spend doing library preps, enabling me to further engage with my research.

about CATS mRNA-seq Kit (with polyA selection) v2 x24, CATS mRNA-seq Kit (with polyA selection) v2 x12, CATS mRNA-seq Kit (with polyA selection) v2 x96.

Given the low input range of up to 1 ng of our cell free plasma derived small RNA samples, commercially available kits and various published protocols failed in generating a library suitable for NGS with attempts resulting in high concentrations of adaptor dimer or failed library amplifications.

In light of this, we are more than happy to have tested the CATS small RNA-seq kit by Diagenode. Even with limited input material we got a rich library with absolutely no detectable adaptor dimer, as expected given it is a ligation free method. The kit performed superbly, in contrast to other commercially available kits or published protocols, with less hassle and with a greater ease of use.

Highly recommended for anyone who is struggling with generating a library from low input and challenging samples.

Established in March 15th 2000, DNA Link, Inc. has developed as one of the leading full genomic service provider with its extensive 17 years of experience. DNA Link has been involved in numerous genomic researches including many national projects, and contributed to the expansion of the genomic industry.

On one hand, DNA Link was the very first company to introduce the RS II system from Pacific Bioscience in Asia, and has been approved as one of the eight global certified service providers for PacBio. Since 2012, DNA Link has been providing quality results that are controlled under strict criteria and successfully assisted numerous research projects.

PacBio platforms’ strongest upside is that it generates the longest reads among all sequencing platforms, and constructing long-read libraries using high molecular weight DNA is the most crucial part of utilizing the platforms. Within the PacBio library preparation process, shearing the DNA molecules accordingly to the library size is the initial step for a successful library construction. Sufficient library yield can be obtained only if the DNA molecules are sheared within the targeted size.

DNA Link has been using the Megaruptor instrument from Diagenode for this shearing process, as it is easy to use and has less contamination risk for using disposable hydropores, which contributes to the overall efficiency of the laboratory logistics.

I have been using Diagenode products to perform ChIP-seq during the last three years and I am very satisfied, with the Bioruptor, the kits and the antibodies. I have used the iDeal ChIP-seq kit for Histones and the iDeal ChIP-seq kit for Transcription Factors with very successful and reproducible results. Once I tried to ChIP histones with a home-made protocol and it worked much worse in comparison with Diagenode kits. In other occasion, I tried a non-Diagenode antibody for a transcription factor and I also got much poor results, however with the Diagenode antibody I always got very nice results. I strongly recommend the use of Diagenode products.

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 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.

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.
