+ChromEMT: Visualizing 3D chromatin structure and compaction in interphase and mitotic cells.

+[[!pmid 28751582 desc="The membrane-permeable anthraquinone dye DRAQ5 (646/697
+nm) was identified by a screen for its capacity to produce singlet oxygen,
+which polymerises diaminobenzidine (DAB), which binds the electron-dense osmium
+tetroxide (OsO4).  Use of this stain suggests that there are 30 nm fibers may
+be rare in vivo or an artefact of chromatin purification.  The authors suggest
+that the absence of higher-order fibers helps compaction, because disordered
+chromatin chains have shorter persistence length."]]
