Acridine Orange hydrochloride (solution) 

Acridine Orange hydrochloride (solution) is a cell-penetrable nucleic acid-selective fluorescent dye. Acridine Orange hydrochloride produces orange fluorescence when it binds to ssDNA or RNA, and green fluorescence when it binds to dsDNA (Ex: 488 nM; Em: green fluorescence at 530 nm, orange fluorescence at 640 nm)^[1][2][3].
Solution Concentration: 10 mg/mL

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs)^[4].
1. Stain cells with Acridine Orange hydrochloride (1 μM; 20 min; 37℃).
2. Wash cells with PBS.
3. Cells are observed by a confocal laser scanning microscopy (FV3000, Olympus).
