C-HiC: A High-Resolution Method for Unbiased Chromatin Conformation Capture Targeting Small Locus.

Abstract

Within the nucleus, precise DNA folding and organization is mandatory for a tight control of gene expression. In the past 20years, a wealth of molecular approaches has unraveled the existence of DNA territories. With the emergence of affordable deep-sequencing approaches, "Cs" techniques such as 4C, 5C, and HiC, to name a few, are now routinely performed by the scientific community in a large number of model systems. We have modified the HiC approach to a capture probe-based version named C-HiC. This updated assay has resulted in an improved throughput analysis, reduced input material, and good repeatability. The protocol described below details our procedure and notes for a C-HiC approach, designed to target only specific portion of a given genome.
