Abstract
Provided herein, among other things, are various compositions and methods for analyzing chromatin. In some embodiments, the composition may comprise a mixture of a nicking enzyme, four dNTPs, at least one labeled dNTP and, optionally, a polymerase. In some embodiments, this method may comprise: obtaining a sample comprising chromatin, reacting the sample with the composition to selectively label the open chromatin in the sample, and analyzing the labeled sample.

A method for detecting open chromatin in fixed or unfixed cell nuclei, comprising:
- (a) reacting a sample containing fixed or unfixed cell nuclei, wherein the cell nuclei comprise chromatin, with:
- (i) a reaction mixture comprising a nicking enzyme, and
- (ii) a ligase and adaptors;
- and
- (b) enriching for, optionally amplifying, and then sequencing DNA fragments that comprise the adaptors.
