Biological Activity: 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[1][2][3][4].
