Chromatin Conformation Capture in High Definition Learn about the Dovetail™ Micro-C Kit

The Dovetail Micro-C Kit enables capture of chromatin topology at a mono-nucleosome resolution. The proximity ligation workflow uses micrococcal nuclease (MNase) for even and highly reproducible chromatin fragmentation with the following benefits:

  • Highest resolution achievable – Capture topological features down to mono-nucleosome positioning
  • Less cost per sample – Create high resolution contacts maps with lower sequencing depth
  • Uniform sequence coverage – no restriction site coverage biases due to use of a sequence-independent MNase enzyme

Dovetail Micro-C Technology represents the next evolution to Hi-C for high-resolution mapping of chromatin topological features.

Improved Signal-to-noise with Dovetail Micro-C:

For identical sequencing depths, the number of supporting reads for known loops are significantly higher for Dovetail Micro-C compared to standard restriction enzyme-based Hi-C approaches. This improves the calling of topological features and reduces the required read depth leading to sequencing cost savings.

Dovetail Micro-C™ Libraries contain nucleosome positioning info:
