Chromatin immunoprecipitation (ChIP) enables the study of DNA-protein interactions. When coupled with high-throughput sequencing (ChIP-seq), this method allows the generation of genome-wide profiles of the distribution of specific proteins in a given cellular context. Typical ChIP-seq experiments require millions of cells as input material and thus are not ideal to study many in vivo cell populations. Here, we describe an ultra-low-input native ChIP-seq method, ULI-NChIP-seq, to profile histone modification patterns in as low as 150 cells.
