Chicago Sky Blue 6B (CAS No. 2610-05-1) is supplied as a blue powder or crystalline material. It has the chemical formula C34H24N6Na4O16S4 and is also commonly known as Direct Blue 1 or Pontamine Sky Blue. This water-soluble synthetic dye readily dissolves to form a blue solution. Chicago Sky Blue 6B is widely used as a counterstain to reduce background autofluorescence in fluorescence microscopy and immunofluorescence histochemistry. The dye exhibits pH-dependent color behavior, appearing blue under neutral to acidic conditions and shifting toward a greenish shade in alkaline environments.

Applications

• Histochemistry and Fluorescence Applications: Chicago Sky Blue 6B is mainly applied as a counterstain in histochemistry, fluorescence microscopy, and immunofluorescence staining to suppress background autofluorescence, thus enhancing visibility and clarity of target structures.
• Vesicular Glutamate Uptake Inhibition: This dye has been known to competitively inhibit vesicular glutamate uptake, which is useful in specialized biochemical and neurobiological research.
• Biological Staining: Used in biological microscopy to improve fluorescence images by reducing non-specific autofluorescence signals.

Key features

• Consistent and Quality Results: Guarantees reliable staining performances in fluorescence histochemistry studies.
• Versatile Usage: Appropriate to be use as a counterstain in the immunofluorescence and fluorescence microscopy methods.
• Consistent Blue Staining: Retains a constant blue color under neutral or acidic pH conditions, leading to better cellular observation.
