DMS produces strong EM contrast in Drosophila cells. Upper panel: Electron micrographs of Clone 8 cells transfected with mCherry-DMS-Histone2Av. The arrowhead points to the stained nucleus of a transfected cell, while untransfected cells are marked with asterisks. The image on the right is a higher magnification version of the one on the left. Lower panels: A cell transfected with mito-DSM. Arrowheads point to mitochondria. The left image shows a cell with mock photo-oxidation reaction with DAB omitted, and the right image shows a cell with heavily stained mitochondria resulting from robust photo-oxidation reaction
