Gram Safranine 5X concentrated stock solution is used for bacterial Gram staining. The solution must be diluted before use and used for counterstaining Gram-negative bacteria. That enables differentiating the blue and purple-colored Gram-positive bacteria from the red-colored Gram-negative bacteria. Apart from use in bacteriology, Safranine O solution can also be used in histology and cytology because it stains cellular nuclei red. It is used for identification of cartilage, mucins, and mastocyte granules. It also enables identification of chondrocytes made from human and rodent mesenchymal stem cells.
