7-AAD
7-AAD is a fluorescent DNA intercalator, which upon binding to dsDNA can be excited by the argon-ion laser and emits at 647 nm (1-3). 7-AAD binds selectively to GC regions of DNA, which makes the dye useful for chromosome banding studies (4).

Acridine Orange, 10 mg/mL in water (high purity) (AO)
Acridine orange (AO) stains dsDNA green (525 nm) and RNA or single stranded DNA red (650 nm).The dye is membrane-permeant and its nucleic acid binding property has been used for cell-cycle studies.

Actinomycin D
Actinomycin D is a nonfluorescent GC-selective intercalator. Similar to 7-AAD (cat. no. 40038), actinomycin D has also been used for chromosome banding studies.

DAPI
DAPI is a popular blue fluorescent DNA dye. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement.

DAPI in H2O, 10 mg/mL
DAPI is a popular blue fluorescent DNA dye. Because of the potential toxicity of DAPI, we offer DAPI dilactate dissolved in H2O as a safer alternative to weighing out the powdery form.

DAPI, dilactate
DAPI dilactate is essentially the same as DAPI dihydrochloride (catalog no. 40011) but with a different counterion.

Ethidium bromide, 10 mg/mL in H2O
Ethidium bromide (EB) is a widely used nucleic acid gel stain although it is also a known potent mutagen. EB is an intercalating DNA-binding dye with little sequence preference.
