Direct Blue 86 (Solvent Blue 38) is a myelin-sheath stain, commonly utilized in microscopy to detect demyelination in the central nervous system. Direct Blue 86 also is a dye with various applications including as a commercial dye in the printing of cotton and mucilage glue fabrics.

Light green SF yellowish (Acid Green 5) is a water-soluble triarylmethane dye. Light green SF yellowish serves as a histological stain that selectively labels mitochondria, collagen, and cartilage, while being an essential component of Papanicolaou staining. Light green SF yellowish is commonly used as a cytoplasmic counterstain for nuclear stains, and is applied in Masson's trichrome staining for collagen fibers, Pap staining, and cytological polychromatic staining in histopathology. Light green SF yellowish also induces growth inhibition and local fibrosarcomas in rats and exerts mild pulmonary tumorigenicity in mice.

Celestine Blue is a electroactive indicator in DNA biosensors. Celestine Blue is strongly adsorbed on the spinel phases and CNT (carbon nanotubes), facilitates dispersion, acts as a capping agent and allows for the fabrication of spinel decorated CNT. Celestine Blue is an efficient charge transfer mediator, which allows for significant improvement of capacitive behavior. TiO₂ nanoparticles doped with Celestine Blue can be used as a label in a sandwich immunoassay for the hepatitis C virus (HCV) core antigen.
