CAS No.: 104821-25-2
Synonyms: Hydroethidine; PD-MY 003
Dihydroethidium, also known as DHE, is a peroxide indicator. Dihydroethidium penetrates cell membranes to form a fluorescent protein complex with blue fluoresces. After entering the cells, Dihydroethidium is mainly localized in the cell membrane, cytoplasm and nucleus, and the staining effect is the strongest in the nucleus. Dihydroethidium produces inherent blue fluorescence with a maximum excitation wavelength of 370 nm and a maximum emission wavelength of 420 nm; after dehydrogenation, Dihydroethidium combines with RNA or DNA to produce red fluorescence with a maximum excitation wavelength of 300 nm and a maximum emission wavelength of 610 nm. 535 nm can also be used as the excitation wavelength for actual observation .

CAS No.: 28718-90-3
Synonyms: 4',6-Diamidino-2-phenylindole dihydrochloride
DAPI (4',6-Diamidino-2-phenylindole) dihydrochloride is a DAPI dye. DAPI is a fluorescent dye that binds strongly to DNA. It binds to the AT base pair of the double-stranded DNA minor groove, and one DAPI molecule can occupy three base pair positions. The fluorescence intensity of DAPI molecules bound to double-stranded DNA is increased by about 20 times, and it is commonly observed with fluorescence microscopy, and the amount of DNA can be determined based on the intensity of fluorescence. In addition, because DAPI can pass through intact cell membranes, it can be used to stain both live and fixed cells . DAPI (Compound 3) is an acid-sensing ion channel 3 (ASIC3) inhibitor. DAPI binds to ASIC3 and blocks the channel function. DAPI can be used in the study of chronic pain treatment (Ex/Em = 356/451 nm).
