Identifying factors bound to specific genomic loci in an unbiased manner is the holy grail of chromatin research, because it would provide an ultimate description of locus function. In this Comment, we explain why purifying a single locus represents a major technical challenge and provide recommendations for achieving this goal. Michiel Vermeulen and Jérôme Déjardin recommend how best to characterize the proteins that bind any specific genomic locus.
