Protocol for Hematoxylin-Eosin (H&E) Staining
Hematoxylin-eosin staining is a routine histological method that stains nuclei mainly blue-purple with hemalum and stains cytoplasm, extracellular matrix, and many stromal components pink with eosin, allowing tissue architecture, cell morphology, necrosis, inflammation, fibrosis, tumor growth pattern, and treatment-associated injury to be evaluated by light microscopy. In cancer cells, primary neurons, mouse tumor models, intestinal organoids, inflammatory macrophage preparations, and drug-screening tissues, H&E is a morphology assay rather than a molecular assay; it should be interpreted with complementary molecular or immunostaining assays when the biological question concerns specific proteins, RNA levels, ferroptosis, mitophagy, or immune phenotypes.
