Acridine Orange hydrochloride is a fluorescent dye of cell-permeable. It binds to nucleic acids, resulting in an altered spectral emission.It is used as a supravital stain and in fluorescence cytochemistry. It may cause mutations in microorganisms.

Acridine Orange Base, a cell-permeable fluorescent dye, selectively stains organisms (bacteria, parasites, viruses, etc.) bright orange and differentiates human cells in green under specific conditions (pH=3.5, Ex=460 nm), facilitating their detection via fluorescence microscopy. It exhibits green fluorescence upon binding to dsDNA (Ex=488, Em=520-524) and turns red with ssDNA (Ex=457, Em=630-644) or ssRNA (Ex=457, Em=630-644), making it useful in cell cycle assays [1] [2] [3].

Acridine Orange 10-Nonyl Bromide is a cardiolipin fluorescent probe (λex: 489 nm, λem: 525 nm).

LysoTracker Red (LysoTracker Red DND-99) is a paraformaldehyde fixable probe that concentrates into acidic compartments of cells and tissues. LysoTracker Red is an indicator of cell death in a manner similar to other standard assays (Annexin, terminal dUTP nick end labeling, Nile blue sulfate, neutral red, and acridine orange). LysoTracker Red is a marker for late endosomes and lysosomes.
