Thiazole orange homodimer (TOhD), also known as TOTO-1, is a cell-impermeant high-affinity nucleic acid stain.

Supplier: AAT BIOQUEST

DiTO™-1 is chemically equivalent to TOTO®-1 (TOTO® is the trademark of Invitrogen).

Thiazole orange has been used for the staining and thereby quantification of reticulocytes.

Supplier: AAT BIOQUEST

Thiazole orange is a fluorescent DNA-binding dye for reticulocyte analysis.

Supplier: AAT BIOQUEST

Thiazole orange is a fluorescent DNA-binding dye for reticulocyte analysis.

Supplier: Biotium

Thiazole orange (TO) is commonly used in reticulocyte analysis to stain residual RNA of blood cells, to stain DNA in agarose gels and capillary electrophoresis. Thiazole Orange stains the yeast nucleus, and is also able to stain bacteria and mammalian cells.

Ethidium homodimer is a red fluorescent dye. It cannot cross an intact plasma membrane, but can easily pass through a damaged plasma membrane. Ethidium homodimer is used to check membrane integrity. One molecule of EthD-1 will non-selectively bind four base pairs in dsDNA.

Supplier: Biotium

The amine reactive succinimidyl ester of TO (thiazole orange) can be conjugated to peptides, proteins, drugs, polymeric materials and biomolecules with primary amine groups. The conjugates are expected to be essentially nonfluorescent until they are able to complex with nucleic acids, resulting in green fluorescence.

Ethidium Homodimer, first developed by Dr. Le Pecq and his colleagues, is a high-affinity fluorescent nucleic acid stain. It binds to both DNA and RNA in a sequence-independent manner and with a >30-fold fluorescence enhancement. The DNA binding of each Ethidium Homodimer covers four base pairs and is believed to occur by intercalation. Because the dye is highly positively charged, it cannot cross cell membranes to stain living cells. It is useful for detecting nucleic acids in solution, or for selectively staining dead cells with damaged plasma membranes.

Orange G, Sigma-Aldrich®

Supplier: Merck

The CERTISTAIN® dry dye Orange G (C.I. 16230) is used for the preparation of a staining solution for Papanicolaou’s staining in cytology in material of human origin. The cytological staining technique developed by Papanicolaou is still the standard method in cancer and hormone cycle diagnosis. The effect of the Orange G staining solution is considerable in smears with keratinized cells under acidic pH conditions, when the obvious orangeophilic cytoplasmic stain is recognizable and may point to the presence of hyperkeratosis, HPV infection or carcinoma cells.
As CERTISTAIN® dye it is chemically quality-certified according to highest standards and strict specifications. As an IVD product and CE registered, it can be used hassle-free in diagnostics and laboratory accreditations.
