Abstract

De novo identification of chromatin interactors can reveal unexpected pathways relevant to physiology and human disease. Inspired by the DNA mediated chromatin pull-down (Dm-ChP) technology (also known as iPOND [isolation of proteins on nascent DNA]) for the proteomic characterization of nascent DNA, we have recently reported a new experimental protocol that allows for the identification of proteins on total DNA (iPOTD) for bulk chromatome profiling and de novo identification of chromatin-bound proteins. Here, we detail a step-by-step protocol to survey the cellular chromatin-bound proteome in a simple, robust, and unbiased manner. For complete details on the use and execution of this protocol, please refer to Aranda et al. (2019).
