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.

PolyFreeze is a water-soluble support matrix and a form of embedding medium for frozen sectioning. PolyFreeze sections flawlessly at routine frozen specimen thickness of 5-6 μ and leaves no slide residue. It provides for -20 ºC cryostat sectioning in rapid set embedment. This medium freezes quickly supporting the tissue for sectioning at 3 mm and up with no cracking of the matrix at temperatures from -8 °C to -25 °C.
