Weigert's elastic stain is a combination of stains used in histology which is useful in identifying elastic fibers. Often orcein or a combination of resorcinol and fuchsine are used for staining. For counterstaining cell nuclei nuclear fast red or hematoxylin is also used. After applying, elastic fibers show up blue colored while cell nuclei ...
The trichrome is applied by immersion of the fixated sample into Weigert's iron hematoxylin, and then three different solutions, labeled A, B, and C: Weigert's hematoxylin is a sequence of three solutions: ferric chloride in diluted hydrochloric acid, hematoxylin in 95% ethanol, and potassium ferricyanide solution alkalized by sodium borate.
Hematoxylin staining shown as "basophilic" at top, seen with dual staining with hematoxylin and eosin (H&E). 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.
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.
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 ]

Hematoxylin and Van Gieson's stain gives collagen a pink color, such as in fibrosis (arrows, here in cirrhosis). Van Gieson's stain is a mixture of picric acid and acid fuchsin . It is the simplest method of differential staining of collagen and other connective tissue .
