What is von Kossa used for?

What is von Kossa used for?

Von Kossa stain is widely used in histology to detect the presence of abnormal calcium deposits in the body. The principle of this coloration is based on the transformation of calcium salts into silver salts: calcium ions, bound to phosphates, are replaced by silver ions brought by a solution of silver nitrate.

What type of stain is von Kossa?

Calcium Stain
The Von Kossa (Calcium Stain) is intended for use in the histological visualization of calcium deposits in paraffin sections.

What does Azan stain?

The Azan staining method stains the collagen fibers within fibrous connective tissue blue.

What does Rhodanine stain?

Rhodanine stain is used in histology to identify copper deposits. The reaction utilizes the property of copper to bind with high affinity to protein copper deposits in tissue sections.

What does warthin Starry stain?

Warthin – Starry stain is a stain based on silver nitrate used in histology. This type of stain is commonly called silver staining. Warthin – Starry stain is used for the visualization of spirochetes but also for the detection of Helicobacter pylori and microsperediates.

Why does collagen stain pink?

Hematoxylin acts as a basic stain via a substance called hematein which is formed in solutions of hematoxylin. It stains nucleic acids in the nucleus (chromatin and nucleolus) and cytoplasm (ribosomes) blue. It is thus mainly a cytoplasmic stain. Collagen and red blood cells stain pinkish or reddish with eosin.

What is Masson’s Trichrome used for?

Standard applications: Masson’s trichrome staining is widely used to study muscular pathologies (muscular dystrophy), cardiac pathologies (infarct), hepatic pathologies (cirrhosis) or kidney pathologies (glomerular fibrosis). It can also be used to detect and analyze tumors on hepatic and kidney biopsies.

What is copper staining?

Copper staining occurs when copper is introduced into the pool from products that contain copper. These include sulphate blocks, copper and silver systems, low-quality pool salts or copper-based algaecides. All of these products add large quantities of invisible copper ions into your pool water.

What is 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 a Steiner stain?

The modified Steiner stain is a non-specific silver stain for identifying bacteria in formalin-fixed, paraffin-embedded tissues. The principle behind its use is that bacteria are first sensitized using uranyl nitrate solution, making them able to precipitate silver from a silver nitrate solution.

What is warthin tumor?

Warthin tumor is a benign tumor of the salivary gland. The first symptom is usually a painless, slow-growing bump in front of the ear, on the bottom of the mouth, or under the chin. Warthin tumors may increase in size over time, but few become cancerous.

What is basophilic and eosinophilic?

Eosinophils (basic components that like acids) are dyed red by the acid stain, eosin. “Basophils” (acid that like base components) are dyed blue by the basic stain, hematoxylin.
