Accurate and cost-effective discovery of active gene regulatory interactions
The Arima-HiChIP protocol is a reproducible and simplified protocol for identifying long-range genomic contacts mediated by proteins. HiChIP combines Hi-C and chromatin immunoprecipitation with antibodies against a protein of interest to enrich for interactions mediated by this protein. As a targeted approach HiChIP has the advantage of requiring less sequencing compared to Hi-C. Whereas Hi-C can potentially detect all types of chromatin interactions, Arima HiChIP targeting H3K27ac or H3K4me, using Arima validated antibodies, is specific for interactions linking active regulatory domains.
