Diagenode

クロマチン断片

ChIPの成功に最も重要なステップは細胞の固定と溶解、そしてクロマチンの断片化の両方です。 研究者の中には、これらのステップの両方の重要な性質を見過すことがあります。断片化工程の不一致を解消するDiagenodeのPicoruptor®は、最先端の超音波ACT(Adaptive Cavitation Technology)を駆使し、効率的にクロマチンを断片します。ACTは、穏やかかつ非常に有効な断片力を用いて、ChIP実験に必須の高いIP効率および感度を持つ最高のクロマチン品質を可能にします。

さらに、Picoruptor®は、タンパク質-DNA複合体が高感度で偏りのない正確なChIPのために十分に保存されるよう、熱分解からクロマチン断片を保存する正確に制御された温度環境を提供します。



Diagenode Picoruptor®は、qPCRやChIP-seqなど、最適に断片化された偏りのないクロマチンが必須な多くのアプリケーションにぴったりのクロマチン断片を実現します。

Panel A, 10 µl volume: Chromatin samples are sheared for 10, 20 and 30 cycles of 30 sec ON/30 sec OFF with the Bioruptor® Pico using 0.1 ml Bioruptor® Microtubes (Cat. No. B01200041). Panel B, 100 µl volume: Chromatin samples are sheared for 10 cycles of 30 sec ON/30 sec OFF with the Bioruptor® Pico using 0.65 ml Bioruptor® Microtubes (Cat. No. WA-005-0500). Panel C, 300 µl volume: Chromatin samples are sheared for 5, 10 and 15 cycles of 30 sec ON/30 sec OFF with the Bioruptor® Pico using using 1.5 ml Bioruptor microtubes (Cat. No. C30010016). Prior to de-crosslinking, samples are treated with RNase cocktail mixture at 37°C during 1 hour. The sheared chromatin is then de-crosslinked overnight and phenol/chloroform purified as described in the kit manual. 10 µl of DNA (equivalent of 500, 000 cells) are analyzed on a 2% agarose gel (MW corresponds to the 100 bp DNA molecular weight marker).
