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.
Acridine orange (AO) is a fluorescent dye with two different staining characteristics. In fixed tissues, it acts as a metachromatic dye and differentially stains DNA (green) and RNA (orange). But, in living cells it acts as a pH indicator and produce brilliant orange-red in acidic condition. AO has been used to identify apoptotic cells in drosophila embryos. Acridine orange staining method has been used to deliver more consistent data in the micronucleus test. It is used a diagnostic assay manufacturing, hematology, histology.
