Fig. 10From: Transcriptionally active chromatin loops contain both ‘active’ and ‘inactive’ histone modifications that exhibit exclusivity at the level of nucleosome clustersDual-labelled super-resolution STORM images of the Y loops: H3K27me3 and H3K4me3. (A-C) different examples are shown from three different nuclei labelled for H3K27me3 (magenta) and H3K4me3 (green). C) shows a dense region of chromatin on the periphery of the nucleolus thought to be near the origin point of the Y loops, and is strongly enriched for both H3K27me3 and H3K4me3. The scale bars are 1 μmBack to article page
