A Chromatin immunoprecipitation assays were performed using JurkatTat LTR-DsRed, clone 11. The cells were treated for 24 h with PH02 and/ or PEP005, and ChIP was performed using antibodies against histone H3K9-me3 (left panel) and histone H3K9-ac (right panel). The results are presented relative to ChIP with anti-histone H3 antibodies.
