Hematoxylin and eosin staining, commonly known as H&E staining, is a cornerstone technique in histology and pathology labs worldwide. Essential for tissue analysis and diagnosis, H&E staining provides critical insights into cellular structures and tissue morphology. At iHisto, we specialize in delivering high-quality hematoxylin and eosin staining services, ensuring accurate and reproducible results for your research needs.
What is Hematoxylin and Eosin (H&E) Staining?
H&E staining combines two essential dyes: hematoxylin and eosin. Hematoxylin, a basic dye, stains nuclei a deep blue-purple, clearly delineating nuclear structures. Eosin stain, an acidic dye, stains cytoplasm, extracellular matrix, and connective tissue components a pink or red hue, providing striking contrast against the nuclei.
Importance of H&E Staining in Histology
The popularity of the h and e stain lies in its simplicity, reliability, and versatility. It allows pathologists and researchers to visualize cellular details and tissue architecture, making it invaluable for diagnosing diseases, understanding tissue changes, and evaluating pathological conditions.
Steps of Hematoxylin and Eosin Staining
The typical procedure for h&e staining involves several key steps:
Tissue Preparation: Tissues are fixed (typically formalin-fixed), embedded in paraffin (FFPE), and thinly sectioned.
Deparaffinization and Hydration: Removal of paraffin and rehydration of tissue sections.
Hematoxylin Staining: Slides are stained with hematoxylin, highlighting nuclei.
Differentiation and Bluing: Excess hematoxylin is removed, and slides are treated to achieve optimal nuclear detail.
Eosin Staining: Sections are counterstained with eosin, clearly defining cytoplasmic and structural elements.
Dehydration and Mounting: Slides are dehydrated, cleared, and mounted for microscopic evaluation.
Common Variations in Terminology
Due to its global use, various terminologies have evolved for this staining method, such as hematoksilin eosin and haematoxylin and eosin. These terms, although varied, refer to the same fundamental staining procedure.
Applications of H&E Staining
Pathological Diagnosis: Used extensively in histopathology for cancer diagnosis and tissue abnormality detection.
Research Applications: Fundamental in biomedical research, particularly in histology, anatomy, and pathology studies.
Veterinary Pathology: Important for diagnosing animal diseases and research involving animal models.
