Common biological dye Safranin O Powder is frequently used for staining in histology and microbiology. Safranin O Powder is used by microbiologists to stain bacterial cells, making it easier to distinguish between Gram-positive and Gram-negative bacteria based on the properties of their cell walls. Gram-negative bacteria lose the stain and turn red or pink after counterstaining, but Gram-positive bacteria keep the stain and appear purple.
In histology, safranin O powder is a key staining agent, especially for identifying cartilage and cell nuclei in histological samples. This staining method allows pathologists and researchers to see cellular characteristics and analyze tissue architecture.
Safranin O powder’s application in leather and textile dyeing, which transcends the domains of histology and microbiology, demonstrates its adaptability.
