EOSIN stain 1% 500ml | Biorays


EOSIN stain 1% is a commonly used histological stain in laboratory settings. It is a solution containing a 1% concentration of eosin dye, a synthetic red dye derived from coal tar. Eosin stain is widely employed in histology and pathology to enhance the visualization and differentiation of cellular structures, particularly in tissue sections.

The key features and uses of EOSIN stain 1% include:

  1. Cytoplasmic Staining: EOSIN stain 1% selectively stains the cytoplasm of cells, imparting a red or pink color to the tissue sections. It helps in distinguishing and highlighting cellular components, including organelles and other cytoplasmic structures.

  2. Contrast Enhancement: By staining the cytoplasm, EOSIN stain 1% creates contrast against other cellular structures, such as nuclei, collagen fibers, and extracellular matrix components. This contrast facilitates the identification and differentiation of various tissue components under a microscope.

  3. Tissue Differentiation: EOSIN stain 1% is often used in conjunction with hematoxylin, a blue dye, in a staining technique called hematoxylin and eosin (H&E) staining. H&E staining is widely employed to visualize and differentiate different tissue types, allowing pathologists and researchers to examine the morphological characteristics of tissues.

  4. Routine Histology: EOSIN stain 1% is a routine stain used in histopathology laboratories to prepare tissue sections for microscopic examination. It is particularly useful in evaluating general tissue architecture, cell morphology, and identifying pathological changes or abnormalities.

  5. Tumor Identification: In cancer diagnostics, EOSIN stain 1% helps in identifying and assessing the characteristics of tumor cells. It aids in the identification of tumor boundaries, cellular differentiation, and the presence of invasive features.

  6. Teaching and Research: EOSIN stain 1% is extensively used in educational and research settings for studying various tissues and their pathological conditions. It enables the examination of tissue samples to understand cellular interactions, disease processes, and evaluate treatment outcomes.
