Abstract:
Regulation of many biological processes in eukaryotes involves distant communication between the regulatory DNA sequences (e.g., enhancers) and their targets over the DNA regions organized in chromatin. However previously developed methods for analysis of communication in chromatin in vitro are artifact-prone and/or do not allow analysis of communication on physiologically relevant, saturated arrays of nucleosomes. Here we describe a method for quantitative analysis of the rate of distant communication in cis on saturated arrays of nucleosomes capable of forming the 30-nm chromatin fibers in vitro.

Chromatin Immunoprecipitation- ChIP
Types of ChIP
ChIP can be divided into two types - X-ChIP and N-ChIP. X-ChIP involves in vivo cross-linking of histones and regulatory proteins to DNA, fragmenting the DNA by sonication, and isolating the protein-DNA...
