What does resorcin fuchsin stain?

What does resorcin fuchsin stain?

PRINCIPLE: The complex formed from the basic fuchsin, an iron resorcin lake, binds to the elastic fibers, resulting in the blue-black staining. The nuclear detail is stained with an iron hematoxylin which will not over differentiate in the acidic elastic stain solution.

What does aldehyde fuchsin stain?

Aldehyde fuchsin is a standard stain for the secretion granules of pancreatic B cells. A series of controlled experiments was undertaken to test the effects of fixatives, oxidation and destaining procedures on aldehyde fuchsin staining of insulin, proinsulin and other proteins immobilized in polyacrylamide gels.

What does Weigert stain stain?

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 is Van Gieson stain used for?

Van Gieson Stain is used to differentiate between collagen and smooth muscle in tumors and to demonstrate the increase of collagen in diseases. This method combines two or more anionic dyes and rely on differential binding by tissue components.

What does Weigert hematoxylin stain?

Weigert’s iron hematoxylin kit – for nuclear staining in histology is a ready to use staining kit used for human-medical cell diagnosis and serves the purpose of the histological investigation of sample material of human origin, for example histological sections of e. g. the liver, the kidney, the intestine, the …

What is Weigert hematoxylin?

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. Our Weigert’s Hematoxylin Kit does not contain mercury.

Is Van Gieson a special stain?

Verhoeff-van Gieson Stain: A Special Histology Stain for Elastic Fibers.

Is Van Gieson a trichrome stain?

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 Biebrich scarlet stain?

Biebrich scarlet-acid fuchsin solution stains all acidophilic tissue elements such as cytoplasm, muscle, and collagen.

Why is Orcein stain used?

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 does Aceto-Orcein stain?

Aceto-orcein stain turns chromosomes a purple-red colour. This stain can be prepared from powder or purchased as solution; staining is best with freshly prepared stain as, over time, the stain precipitates and changes colour from a deep red or burgundy colour to a brownish colour.
