TESTIMONIAL

One of our issues was that we could obtain only a limited number of cells, which is not enough for canonical ChIP-seq protocols. To solve this issue, we used the Diagenode ChIPmentation solution composed of iDeal ChIP-seq Kit for Transcription Factor, TAG Kit for ChIPmentation, and 24 SI for ChIPmentation. We performed ChIPmentation with IP-Star automated system for GATA6 in 2 million GATA6-overxpressing iPS cells. The result showed clear signal/noise ratio and was highly reproducible. This solution also worked in vitro differentiated definitive endoderm cells (data not shown).

    We were very happy with the method.  It gave good results in the end, and required much smaller samples than we need to reliably perform conventional ChIP-seq.
    In our view, the main advantages of the ChIPmentation kit compared to our conventional ChIP-seq protocol are (most important first):

    • smaller sample requirement,
    • simpler workflow with less that can go wrong,
    • slightly higher resolution and signal: noise ratio.

    Researcher from University of Nice-Sophia Antipolis, Nice, France

    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.

    Dr. Francisca Martinez Real - Development and Disease Research Group - Max Planck Institute for Molecular Genetics, Berlin, Germany

    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.

    Researcher at Johns Hopkins University, School of Medicine

    There are so many ChIP-related products on the market, but I feel so lucky that I have been using the ones from Diagenode since I started my CHIP-seq project. I have used their iDeal CHIP-seq Kit for Transcription Factors and MicroPlex Library Prep Kit v2. Both of them are fantastic and very reproducible. With the very-well written protocols, you will just be home and dry. Particularly, I want to thank the technical support, who is very patient, knowledgeable and extremely helpful. I would definitely recommend my colleagues to use the CHIP products from Diagenode.

    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.
