Abstract:
Improvements in chromatin immunoprecipitation-high throughput sequencing techniques has allowed the creation of chromatin maps from limited biological sample sizes that cannot be evaluated using conventional chromatin immunoprecipitation-sequencing protocols. For example, a modified universal primer is utilized that incorporates restriction enzymes into chromatin immunoprecipitation fragments before amplification. The improved method allows the sample sizes to be several orders of magnitude less than that required for standard ChIP-Seq techniques.
