Acridine orange hemi (zinc chloride) salt has been used to stain primary human umbilical vein endothelial cells (HUVEC) and is used in micronucleus tests (MNTs). Acridine orange, a cell-permeable metachromatic fluorescent cationic dye that intercalates DNA and RNA, is used in fluorescence and epiflouresence microscopy. Acridine orange dye has been used to analyse mitochondria and lysosomal content by flow cytometry, characterise multidrug resistance, and measure changes in mitochondrial mass during apoptosis in rat thymocytes.

Xylene cyanol is often used as a tracking dye during agarose or polyacrylamide gel electrophoresis. It has a slightly negative charge and will migrate in the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The tracking dye typically migrates with the DNA molecules around 5 kb. Xylene cyanol may also be used in loading buffer that facilitates the observation of the sample during gel loading and electrophoresis.
