The recipes emerged from Claude L. Pierre Masson's (1880–1959) original formulation have different specific applications, but all are suited for distinguishing cells from surrounding connective tissue. Most recipes produce red keratin and muscle fibers, blue or green collagen and bone, light red or pink cytoplasm, and dark brown to black cell ...
In "one-step" methods, all the dyes—with or without a polyacid—are combined in a single solution. One of the oldest single-step approaches to trichrome staining is van Gieson's method, which stains muscle and cytoplasm yellow, and collagen red. Another is the Gömöri trichrome stain, which closely mimics Masson's trichrome. In "yellowsolve ...
Sirius Red F 3B (Direct Red 80) is an azo dye primarily used in staining methods for collagen and amyloid. [1] It has the molecular formula C 45 H 26 N 10 Na 6 O 21 S 6.. In histology, sirius red staining is used in various domains of diagnostic to observe fibrosis levels in a lot of cases of inflammation induced by cancer, vascular or metabolic pathologies.

A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .
It is similar to Masson's trichrome stain, but it uses Biebrich scarlet for the plasma stain. It was initially published by Ralph D. Lillie in 1940. [ 1 ] It is applied by submerging the fixated sample into the following three solutions: [ 2 ] Weigert's iron hematoxylin working solution, Biebrich scarlet solution, and Fast Green FCF solution.
Main staining types when using hematoxylin and eosin (H&E). A Basophil granulocyte stains dark purple upon H&E staining. Basophilic is a technical term used by pathologists. It describes the appearance of cells, tissues and cellular structures as seen through the microscope after a histological section has been stained with a basic dye.
Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears , urine samples, and bone marrow aspirates , which are examined under a light microscope .
