An Optimized Protocol for ChIP-Seq from Human Embryonic Stem Cell Cultures

Chromatin immunoprecipitation (ChIP) followed by next-generation sequencing is a powerful technique that characterizes the genome-wide DNA-binding profile of a protein of interest. The general ChIP-seq workflow has been applied widely to many sample types and target proteins, but sample-specific optimization of various steps is necessary to achieve high-quality data. This protocol is specifically optimized for cultured human embryonic stem cells (hESCs), including steps to check sample quality and non-specific enrichment of "hyper-ChIPable" regions prior to sequencing. For complete details on the use and execution of this protocol, please refer to Gunne-Braden et al. (2020).
