COMPOSITION DE COLORANT POUR EXAMINATIONS HYSTOLOGIQUES

The invention relates to a new dyestuff composition for histological examinations, which comprises (1) a product formed by the interaction of one molar proportion of one or more thionine dyestuffsselected from thionine (Colour Index 52,000), toluidine blue (Colour Index 52,040) and dimethyl thionine...

More Information
Summary:The invention relates to a new dyestuff composition for histological examinations, which comprises (1) a product formed by the interaction of one molar proportion of one or more thionine dyestuffsselected from thionine (Colour Index 52,000), toluidine blue (Colour Index 52,040) and dimethyl thionine (Azur A) with at least 0.2 molar proportion of resorcine at elevated temperature, (2) 0.5 to 2 moles of a dyestuff "A", calculated for one mole of the thionine dyestuff interacted with resorcine, and (3) 0.5 to 2 moles of a dyestuff "B", calculated for one mole of the thionine dyestuff interacted with resorcine, wherein dyestuff "A" and dyestuff "B" are alkaline dyestuffs different in colour and pH, and both dyestuff "A" and dyestuff "B" can be mixtures of alkaline dyestuffs similar in colour and pH. The new dyestuff compositions according to the invention enable one to perform a wide variety of hisotlogical examinations much more quickly, simply and safelyb than before, and can also be applied to detect histological changes which could not be detected before.
