🔬 Common Scientific Applications
🧫 Histology & microscopy counterstain: Classic Gram stain counterstain (renders Gram-negative cells red/pink).
🧴 Cartilage matrix staining: Safranin O–Fast Green protocols to visualize/quantify GAGs in cartilage and tissue-engineering sections.
🌿 Plant & wood anatomy: Stains lignified and cutinized cell walls; xylem/vascular structure contrast.
🔬 Fluorescence imaging: Cationic fluorescent dye (typical Ex ~520–535 nm, Em ~580–620 nm; matrix/pH dependent).
📊 Spectrophotometric reference: Strong visible absorbance for method checks and dye-binding assays.
🧪 Microbiology workflows: General counterstain and viability/contrast roles in selected staining protocols.
🧷 Materials & thin films: Dye-doped polymers/sol-gels for optical coatings, sensors, and waveguides.
⚡ Photophysics/redox studies: Model dye for photobleaching, solvent-polarity effects, and redox behavior.
R&D use only. Staining intensity depends on pH, fixation, and protocol (e.g., mordants/counterstains). Verify spectra and handling in your SDS/CoA and method notes.
