acridine red

Acridine red is an indicator of fluorescent.

Acridine Orange base is a cell-permeable fluorescent dye that binds to nucleic acids and emits different colors of fluorescence, which exhibits green fluorescence when bound to dsDNA (Ex=488 nm, Em=520-524 nm) and red fluorescence when bound to ssDNA or ssRNA (Ex=457 nm, Em=630-644 nm) and can be used for cell cycle analysis and apoptosis detection.
