What is Gills haematoxylin?
Gill’s Hematoxylin is a specially formulated solution of hematoxylin designed for use as a biological stain for the chromatin of normal and abnormal cells, whether in whole cells or sections of animal or human tissue.
What is progressive hematoxylin?
Generally, progressive haematoxylins are less concentrated. Hence, they slowly and selectively stain chromatin. In progressive staining, haematoxylin primarily stains the chromatin to the desired intensity. Thus, it does not require differentiation in dilute acid alcohol to pull out the excess stain.
Is Harris hematoxylin a progressive stain?
Harris hematoxylin is another commonly used alum hematoxylin that may be used for progressive staining of cytology specimens but can also be used for either progressive or regressive staining in histology. The staining tends to provide clear nuclear detail.
What is progressive staining?
n. A procedure in which stain is applied until the desired intensity of tissue coloration is attained.
What is hematoxylin staining 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.
What is the difference between Mayer and Harris hematoxylin?
The key difference between Harris and Mayer’s haematoxylin is that Harris haematoxylin is used in regressive staining while Mayer’s haematoxylin is used in progressive staining. Haematoxylin is a basic dye that is commonly used in histopathology. It is a natural dye extracted from the tree Haematoxylon campechianum.
What is Harris hematoxylin stain?
HARRIS HAEMATOXYLIN nuclear stain is designed to stain nuclei of cells derived from the human body. The stained cell sample is used to facilitate the diagnosis of the pathological state, and is intended for in-vitro examination of cellular deformity.
What color is hematoxylin stain?
deep blue-purple color
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.
What does Mayer’s hematoxylin stain?
It is often used as a nuclear counterstain for special stains and immunohistochemistry. For these applications, Mayer’s is used to stain the nuclei and then blued without the use of a differentiator. Mayer’s is also a water-based stain.
What is Ehrlich’s hematoxylin?
Hematoxylin (Ehrlich) solution contains the dye, hematin and the Aluminum potassium sulfate as a mordant which provides the stain colour (blue) glacial acetic acid controls the pH of the Solution. It can be used as nuclear counter stain (as in PAS staining etc.)
What does Weigert haematoxylin stain?
Weigert´s Iron Hematoxylin Stain Kit is a nuclear staining solution containing, hematoxylin, ferric chloride and hydrochloric acid used in many non-routine techniques (special stains) because, it resists decolorization in acidic staining solutions.
What are types of haematoxylin?
Although the stain is commonly called haematoxylin, the active colourant is the oxidized form haematein, which forms strongly coloured complexes with certain metal ions (commonly Fe(III) and Al(III) salts)….Haematoxylin.

What does Orcein stain?
Orcein stain is a staining technique used for the visualization of hepatitis B surface antigens (HBsAg), elastic fibers and copper-bound proteins. Viral particles present inside host cells are called viral inclusion bodies.
What is Ehrlich’s haematoxylin?
What is Gill hematoxylin stain?
Newcomer Supply Hematoxylin Stain, Gill, is a ready to use progressive nuclear stain available in three strengths for cytology and histology applications. Due to the progressive staining nature of Gill hematoxylin, over-staining is less likely and a differentiation step is not required.

Do I need to filter Gill hematoxylin?
Gill hematoxylin does not require filtering but if using any Gill hematoxylin for cytology specimen staining, filtering before each use is highly suggested to prevent solution contamination. Gill I is termed “single strength”. ideal for both gynecological and non-gynecological cytology preparations.
