ChIP-MS reveals the local chromatin composition by label-free quantitative proteomics

ABSTRACT: Chromatin immunoprecipitation (ChIP) has been a cornerstone for epigenetic analyses over the last decades, but even coupled to sequencing approaches (ChIP-seq), it is ultimately limited to one protein at a time. In a complementary effort, we here combined ChIP with label-free quantitative (LFQ) mass spectrometry (ChIP-MS) to interrogate local chromatin compositions. We demonstrate the versality of our approach at telomeres, with transcription factors, in tissue and by dCas9-driven locus-specific enrichment.
