Luxol fast blue stain, abbreviated LFB stain or simply LFB, is a commonly used stain to observe myelin under light microscopy, created by Heinrich Klüver and Elizabeth Barrera in 1953. [1] LFB is commonly used to detect demyelination in the central nervous system (CNS), but cannot discern myelination in the peripheral nervous system .
Cresyl violet is used to stain Heinz bodies in red blood corpuscles or for staining of the neurons in the brain and spinal cord. It is used to demonstrate the Nissl substance in the neurons and cell nuclei. In this role it is also often used as a counterstain to Luxol fast blue, which stains the myelin.
Photomicrograph of Nissl bodies (two are indicated by arrows) in the cytoplasm of motor neurons in the anterior horn of the spinal cord; cresyl violet stain (purple) along with a luxol fast blue stain for myelin. Scale bar = 30 microns (0.03mm). Drawing of a motor neuron from the ventral horn of the medulla spinals of a rabbit.
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.
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.

It is used to stain collagen. If blue is preferred to green, methyl blue or water blue can be substituted. Standard applications: Masson's trichrome staining is widely used to study muscular pathologies (muscular dystrophy), cardiac pathologies , hepatic pathologies or kidney pathologies (glomerular fibrosis). It can also be used to detect and ...
