The stain has been unchanged for many years because it works well with a variety of fixatives and displays a broad range of cytoplasmic, nuclear, and extracellular matrix features. Hematoxylin has a deep blue-purple color and stains nucleic acids by a complex, incompletely understood reaction. Eosin is pink and stains proteins nonspecifically. In a typical tissue, nuclei are stained blue, whereas the cytoplasm and extracellular matrix have varying degrees of pink staining. Well-fixed cells show considerable intranuclear detail. Nuclei show varying cell-type- and cancer-type-specific patterns of condensation of heterochromatin hematoxylin staining that are diagnostically very important.
We continue to use this simple and essential stain today, which has remained unchanged for well over a century.

The format is easily reproduced and the reagents resilient enough to allow for large numbers of slides to be stained consistently before reagents need to be changed. In the past, stains and their components were routinely made by the laboratory. Commercially available, premade reagents were uncommon and expensive.
Structures that stain readily with eosin are termed hondapeople.org is most often used as a counterstain to haematoxylin in H&E. (haematoxylin and eosin).
The hematoxylin stains cell nuclei blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. This stain combination was first introduced in by A. After tissues have been collected often as biopsies and fixed, they are typically dehydrated and embedded in melted paraffin wax , the resulting block is mounted on a microtome and cut into thin slices.
This stain has been unchanged for many years because it works well with a variety of fixatives and displays a broad range of cytoplasmic, nuclear, and extracellular matrix features. So far it is still the most widely used stain in medical diagnosis and is often the gold standard. Hematoxylin is a compound extracted from the heartwood of the logwood tree. Haematoxylin can be considered as a basic dye. It is used to stain acidic structures a purplish blue. DNA in the nucleus, and RNA in ribosomes and in the rough endoplasmic reticulum are both acidic, and so haemotoxylin binds to them and stains them purple. Haematoxylin alone is not technically a dye, and will not directly stain tissues.
