The Future of Protein–DNA Mapping (Mitch Guttman)

In this episode of the Epigenetics Podcast, we talked with Mitch Guttman from Caltec about ChIP-DIP (ChIP-Done In Parallel).

ChIP-DIP is a newly developed approach for high-resolution protein–DNA interaction mapping. The method uses antibody-guided isolation of denaturant-insoluble protein–DNA complexes, resulting in substantially improved specificity and peak definition compared with conventional ChIP-seq. We explore why denaturation resistance is central to the workflow, how the method performs across transcription factors, chromatin regulators, and histone marks, and what experimental parameters determine its success. The conversation also covers current limitations, practical adoption details, and perspectives on how ChIP-DIP fits into the broader landscape of chromatin profiling technologies.
