What does Weigert stain stain?
What does Weigert stain stain?
Definition. The Weigert stain involves the treatment of nervous tissue with potassium dichromate to preserve myelin lipids. The lipids are then stained with the use of hematoxylin, providing a useful technique for visualizing fiber pathways. The pathways appear black due to the staining of myelin sheaths.
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 stains for elastin?
The most commonly used stains are Weigert’s resorcin fuchsin; Verhoeff’s hematoxylin, iodine, and ferric chloride; orcein; and Gomori’s aldehyde fuchsin [12. Elastic fibers in scar tissue.
What stain shows elastic fibers?
The Verhoeff stain
The Verhoeff stain is one of the most commonly-used stains to visualize elastic tissue, as found in blood vessel walls, elastic cartilage, lungs, skin, bladder, and some ligaments.
What is a Weigert section?
: a method of tracing the course of medullated nerve fibers by hardening the tissues in a solution of potassium dichromate and staining the sections for myelin sheaths.
What is Van Gieson stain used for?
Van Gieson’s trichrome is used for the differentiation between collagen and smooth muscle in tumors and to demonstrate the increase in the amount of collagen in these pathologies.
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 EVG stain used for?
PURPOSE: This stain is useful in demonstrating atrophy of elastic tissue in cases of emphysema, and the thinning and loss of elastic fibers in arteriosclerosis, and other vascular diseases.
What Colour does the elastin stain?
Elastic fibers and cell nuclei are stained black, collagen fibers are stained red, and other tissue elements including cytoplasm are stained yellow.
