title: Strategies for the reconstitution of chromatin.
abstract: In eukaryotes, chromatin is the natural form of DNA in the nucleus. For hundreds of millions of years, DNA-binding factors have evolved with chromatin. It is therefore more desirable to study the molecular mechanisms of DNA-directed processes with chromatin than with naked DNA templates. To this end, it is necessary to reconstitute DNA and histones into chromatin. Fortunately, there are a variety of methods by which a nonspecialist can prepare chromatin of high quality. Here, we describe strategies and techniques for the reconstitution of chromatin in vitro.
