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 (hemizinc salt) 85% (dye content), Sigma-Aldrich®

Supplier: SIGMA-ALDRICH MICROSCOPY
Description: Acridine orange hemi (zinc chloride) salt has been used to stain primary human umbilical vein endothelial cells (HUVEC) and is used in micronucleus tests (MNTs). Acridine orange, a cell-permeable metachromatic fluorescent cationic dye that intercalates DNA and RNA, is used in fluorescence and epiflouresence microscopy. Acridine orange dye has been used to analyse mitochondria and lysosomal content by flow cytometry, characterise multidrug resistance, and measure changes in mitochondrial mass during apoptosis in rat thymocytes.

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.
