A chromatin immunoprecipitation (X-ChIP) assay against the histone mark H3K4me3 for the model organism Exaiptasia diaphana is presented. The specificity and effectiveness of the assay are confirmed by quantitative PCR and next-generation sequencing. This protocol enables the increased investigation of protein-DNA interactions in the sea anemone E. diaphana.
