Updated on March 01, 2026
Iron hematoxylin was the stain used for most of the original morphological descriptions of intestinal protozoa found in humans. The iron hematoxylin staining method can stain the intracellular and nuclear structure’s dark compared to the cytoplasm, for easy identification of parasite morphologies.
What are the components of iron hematoxylin stain?
Reagents required for Iron-Hematoxylin Stain
- Mercuric Chloride.
- Distilled water.
- Ethyl alcohol.
- Hematoxylin.
- Iodine.
- Alcoholic iodine.
- Ferric Ammonium Sulfate (Iron Alum)
- Hydrochloric acid.
What are the two main iron hematoxylin solutions?
Iron Hematoxylin Solutions. Two main Iron Hematoxylin solutions are employed for routine work in the laboratory: Weigert’s Solution, using Ferric Ammonium Chloride, and Heidenhain’s Solution, using Ferric Ammonium Sulfate (Iron Alum) as mordants.
What is the function of iron in Weigert’s hematoxylin?
Iron hematoxylin solutions (e. g. Weigert’s iron hematoxylin), on the other hand, are acid-resistant and are preferentially used for staining nuclei in histological tissue sections in which counterstaining is done with acidic staining solutions.
What is hematoxylin used for?
H and E staining helps identify different types of cells and tissues and provides important information about the pattern, shape, and structure of cells in a tissue sample. It is used to help diagnose diseases, such as cancer. Also called hematoxylin and eosin staining.
Where does hematoxylin come from?
Hematoxylin is a basic dye derived from the heartwood of Palo de Campeche ( Haematoxylum campechianum), the logwood tree native to Mexico and Central America.
Which hematoxylin uses an iron mordant?
Commonly used Hematoxylins: Their Oxidizers and Mordants
| Hematoxylin | Oxidizer | Mordant |
|---|---|---|
| Heidenhain’s | Ferric ammonium sulfate | Ferric ammonium sulfate |
| Weigert’s | Ferric chloride | Ferric chloride |
What is the use of hematoxylin stain?
Hematoxylin is used to illustrate nuclear detail in cells. Depth of coloration is not only related to the amount of DNA in the nuclei but also to the length of time the sample spends in hematoxylin. Hematoxylin is a reasonably simple dye to make. The dye itself is extracted from the tree Haematoxylum campechianum.
How is hematoxylin obtained?
What does Weigert’s hematoxylin stain?
ron hematoxylin solutions are used for staining nuclei of tissue sections, e.g. elastic fibers stained according to van Gieson or connective tissue stained by various trichromo staining techniques, where acidic stains were used as counter-stain.
What is the pH of hematoxylin?
The pH and peak of absorbance of the aliquots were pH = 2.0 450 NM, 2.5 505, 2.6 507, 2.7 515, 2.8 520, 2.9 530, 3.0 540, 3.1 550, 3.3 560, 3.5 560. In the stained material in the intensity of nuclear staining was about the same at all pH levels but non-specific staining was greatest in slides stained at pH = .
Why is iron hematoxylin used to stain intestinal protozoa?
Iron hematoxylin was the stain used for most of the original morphological descriptions of intestinal protozoa found in humans. The iron hematoxylin staining method can stain the intracellular and nuclear structure’s dark compared to the cytoplasm, for easy identification of parasite morphologies.
What is a hematoxylin stain?
Hematoxylin and Eosin stain is the primary diagnostic stain used in histology and Histopathology including application in the Fine-needle Aspiration Biopsies, Paraffin Fixed embedded tissue.
What is the nature of the extraction of hematoxylin?
Hematoxylin is extracted from the heartwood of the logwood tree Hematoxylum campechianum, when oxidized, it forms the Hematein, a compound that forms the strongly colored complexes with certain metal ions, mainly Iron (Fe) and Aluminium (Al) salts, Metal-Hematein complexes are used to stain the cell nuclei prior to examination under the microscope.
What is the purpose of a hematoxylin test?
Hematoxylin is used to demonstrate the nuclear of the cell and its content, by observing the depth of the color of dye and the time of sample suspension in the dye. Hematoxylin and eosin are both dyes, and naturally, dyes have a high affinity for tissues, depending on the Acidity and/or alkalinity of the dyes.
