🔬 Common Scientific Applications
🧫 Nuclear stain in histology (H&E): Alum/iron–mordanted lakes for crisp DNA/RNA contrast in paraffin sections.
🔬 Cytology (Pap) staining: High-definition nuclear detail and chromatin pattern assessment.
⚗️ Formulation studies: Component in Harris, Mayer, Gill, Weigert’s iron hematoxylin; progressive vs. regressive protocol optimization.
🔄 Oxidation/ripening research: Hematoxylin → hematein conversion, auto-oxidation control, preservative and shelf-life studies.
🔵 Bluing optimization: Evaluation of bluing reagents (e.g., Scott’s substitute, ammonia water) and pH/buffer effects.
🧪 Stain QC & calibration: Batch-to-batch standardization, colorfastness, section thickness/processing checks, proficiency testing.
🌿 Plant & mycology staining: Structural contrast in plant tissues (xylem/phloem) and fungal elements with suitable mordants.
📷 Imaging method development: Brightfield contrast tuning, spectral characterization, and workflow reproducibility.
