Description

Direct Blue 67 is a polarizer that is used as a pre-staining agent for the detection of microorganisms in histology. Direct Blue 67 reacts with the hydroxyapatite in bone to produce an intense blue color, which makes it useful for staining bone sections. The reaction mechanism involves the hydrolysis of the dye by trichloroacetic acid and hematein. This product has been shown to be effective when used with a polymer film and organic solvent or in liquid crystal composition. It has also been shown to react with hematoxylin, producing a blue color that can be used for staining bone sections. Direct Blue 67 is activated by light and has fluorescence properties.
