          DescriptionORANGE G (C.I. 16230) FOR MICROSCOPY CER
          OverviewThe 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.
