Orange G, Certistain® for microscopy, Sigma-Aldrich®

Catalog Number: (1.15925.0025)
Supplier: Merck
Description: 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.

Acridine orange (chlorid salt), hydrate ≥98% (by HPLC), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Acridine orange is a metachromatic dye which can stain DNA, RNA and acid glycosaminoglycans. At low concentrations, it intercalates into DNA and precipitates RNA. However, at high concentrations it denatures and precipitates both RNA and DNA. Acridine orange is also used to analyse autophagy. It enters into acidic organelles in a pH-dependent manner. At neutral pH, acridine orange gives a green fluorescence and in acidic conditions, it accumulates in acidic organelles giving a bright red fluorescence.

Xylenol orange tetrasodium salt in ACS Reagent grade water, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Xylenol orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.
