Tissue staining is a vital technique in biological research, enhancing the visibility of cellular structures for microscopic analysis. It involves applying stains to tissues, which bind to specific components, aiding in the study of cellular functions and disease diagnosis. The process includes fixation, processing, embedding, sectioning, and antigen retrieval, followed by staining. Stains like Hematoxylin and Eosin are crucial for differentiating tissue types and understanding pathological changes.

Staining methods can be categorized as direct, where the dye is applied directly to the tissue, or indirect, where a mordant is used to fix or intensify the stain's binding
Direct and indirect staining techniques are commonly used in histology and cytology to distinguish between different tissue components
Staining methods are invaluable for educational purposes, clinical pathology, and forensic science
Hematoxylin, a basic dye, stains acidic nuclear structures blue or purple, while eosin, an acidic stain, imparts a pink or red color to basic components
Gram staining is a critical technique for classifying bacteria based on their cell wall properties, with Gram-positive bacteria appearing violet and Gram-negative bacteria appearing pink or red after staining
