DNA/RNA Dyes & Nuclear Stains
For nuclear staining of live cells, we offer NucSpot® Live stains available in green or far-red, and RedDot™1, a far-red nuclear stain.
For nuclear staining of fixed cells, see NucSpot® 470, a green nuclear stain, and RedDot™2, a far-red nuclear dye.
Biotium offers a series of asymmetric cyanine dyes, equivalent to SYBR® Green and others: Thiazole Green (aka SYBR® Green I), Thiazole Orange, Thiazole Orange Homodimer (aka TOTO®-1), Thiazole Orange Iodide (aka TO-PRO®-1), Oxazole Yellow (aka YO-PRO®-1), Thiazole Red (aka TO-PRO®-3), and Thiazole Red Homodimer (aka TOTO®-3).
Ethidium Homodimer III (EthD-III) is a far-red dead-cell stain, also sold together with a live cell stain.
We also offer classical nuclear stains such as DAPI, Hoechst, Propidium Iodide (PI), 7-AAD, and Acridine Orange (AO).

7-AAD
7-AAD (7-aminoactinomycin D) is a fluorescent DNA binding dye that is membrane impermeant and therefore generally excluded from viable cells.

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 for improved water solubility.

DMAO, 2 mM in DMSO
DMAO, 2 mM in DMSO is a green-fluorescent nucleic acid dye for staining live bacteria.

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.

Ethidium Homodimer III (EthD-III)
Ethidium Homodimer III was developed by Biotium as an alternative to Ethidium Homodimer I. It has absorption and emission spectra similar to those of Ethidium Homodimer I, but stains DNA 45% brighter.
