Hematoxylin and eosin stain (or haematoxylin and eosin stain or hematoxylin-eosin stain; often abbreviated as H&E stain or HE stain) is one of the principal tissue stains used in histology. [ 1 ] [ 2 ] [ 3 ] It is the most widely used stain in medical diagnosis [ 1 ] and is often the gold standard . [ 4 ]
Haematoxylin stain is commonly followed (or counterstained) with another histologic stain, eosin. [ 10 ] [ 11 ] [ 1 ] When paired, this staining procedure is known as H&E staining , and is one of the most commonly used combinations in histology .
Basic dyes are cationic, i.e. contain positive charges, and thus they stain anionic structures (i.e. structures containing negative charges), such as the phosphate backbone of DNA in the cell nucleus and ribosomes. [1] "Basophils" are cells that "love" (from greek "-phil") basic dyes, for example haematoxylin, azure and methylene blue ...
Phosphotungstic acid haematoxylin (PTAH) is a mix of haematoxylin with phosphotungstic acid, used in histology for staining. It stains some tissue in contrasting colors in a way similar to haematoxylin and eosin stain , as phosphotungstic acid binds to tissue proteins .
Main staining types when using hematoxylin and eosin (H&E), where acidophile cells stain eosinophilic. Acidophile (or acidophil, or, as an adjectival form, acidophilic) is a term used by histologists to describe a particular staining pattern of cells and tissues when using haematoxylin and eosin stains. Specifically, the name refers to ...
Phosphotungstic acid is used in histology for staining specimens, as a component of phosphotungstic acid haematoxylin, PTAH, and “trichrome” reagents, and as a negative stain for imaging by a transmission electron microscope. [citation needed] Phosphotungstic acid haematoxylin
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.
Lillie's trichrome is a combination of dyes used in histology. 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 ]
