Chromatin Profiling of Human Naïve Pluripotent Stem Cells.

Chromatin immunoprecipitation combined with high-throughput sequencing (ChIP-sequencing) facilitates the genome-wide mapping of DNA sequences that are enriched for specific chromatin-binding proteins or histone post-translational modifications. More recently developed chromatin profiling methods called Cleavage Under Targets and Release Using Nuclease (CUT&RUN) and Cleavage Under Targets and Tagmentation (CUT&Tag) have adapted the ChIP-sequencing approach to produce similar data from a smaller amount of starting material, and while overcoming many of the conventional drawbacks of ChIP-sequencing. Here, we present detailed protocols for ChIP-seq, CUT&RUN, and CUT&Tag to profile genome-wide protein-DNA interactions in naïve human pluripotent stem cells.
