What does Movat stain for?
Movat Pentachrome Stain Kit (Modified Russell-Movat) ab245884 is intended for use in histological demonstration of collagen, elastin, muscle, mucin and fibrin in tissue sections. This procedure is particularly useful when studying the heart, blood vessels and various vascular diseases.
What is Movat pentachrome stain?
Movat pentachrome is a staining that makes it possible to highlight the collagen fibers. It is sometimes requested in cardiovascular pathology because it is adapted to the staining of the heart and the blood vessels.
What is pentachrome?

What does Picrosirius red stain?
Picrosirius red (PSR) staining is a commonly used histological technique to visualize collagen in paraffin-embedded tissue sections. PSR and autofluorescence images are used to calculate area of collagen and area of live cells in the tissue; empty spaces (holes) in tissue are considered.
What stains with Mucicarmine?
The Mucicarmine stain is also used to differentiate between mucin negative squamous cell carcinoma and mucin positive adenocarcinoma.
How does Giemsa stain work?
Giemsa solution is composed of eosin and methylene blue (azure). The eosin component stains the parasite nucleus red, while the methylene blue component stains the cytoplasm blue. The thin film is fixed with methanol. De-haemoglobinization of the thick film and staining take place at the same time.
What is a special stain?
Definition of “Special Stain” “Special stains” are processes that generally employ a dye or chemical that has an affinity for the particular tissue component that is to be demonstrated. They allow the presence/or absence of certain cell types, structures and/or microorganisms to be viewed microscopically.
What are the Special stains in histopathology?
Special stains in histopathology. 2. H&E stain is routine stain. – It is the preliminary or the first stain applied to the tissue sections – Gives diagnostic information in most cases. A special stain is a staining technique to highlight various individual tissue component once we have preliminary information from the H&E stain.
What types of stains are available to demonstrate pathologic processes?
There are a wide variety of special stains to demonstrate pathologic processes. They generally employ a dye or chemical which has an affinity for the particular tissue component to be demonstrated. Special Stains available include: 1. Connective Tissue Stains
Why is special staining not as popular as H&E staining?
The variety of stains also means that special staining is not as automated as H&E staining. While many larger laboratories do use automated instruments for the more common stains, they still have an area for hand staining. The complexity of some stains also works against the uses of automation.
What stain is used to stain for neoplasm?
Delicate reticular fibers, which are argyrophilic, can be seen. A reticulin stain occasionally helps to highlight the growth pattern of neoplasms. There are a variety of “Romanowsky-type” stains with mixtures of methylene blue, azure, and eosin compounds.
