Cresyl violet stained partial brain section of a Macaque. It is used in biology and medicine as a histological stain. Cresyl violet is an effective and reliable stain used for light microscopy sections. Initially, tissue sections are "defatted" by passing through graded dilutions of ethanol. Then, rehydrated by passing back through decreasing ...
Thioflavin S stain (left in green) and amyloid-Beta antibody immunocytochemistry (right) on adjacent sections of the hippocampus of a patient suffering from Alzheimer's disease. Thioflavin S binds both senile plaques (SP) and neurofibrillary tangles (NFT), the two characteristic cortical lesions of Alzheimer's.
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]
A fascinating map shows the most searched for cost for a product or service by state. It was created by local business listing service Fixr.com by Googling "how much does an a * cost" in a certain ...
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.
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.
Thus a supravital stain may have a greater toxicity, as only a few cells need to survive it a short while. The term "vital stain" is used by some authors to refer specifically to an intravital stain, and by others interchangeably with a supravital stain, the core concept being that the cell being examined is still alive. As the cells are alive ...
These dyes intensely stain "Nissl bodies" (rough endoplasmic reticulum), which are abundant in neurons and reveal specific patterns of cytoarchitecture in the brain. Other common staining techniques used by histologists in other tissues (such as the hematoxylin and eosin or " H&E stain ") leave brain tissue appearing largely homogeneous and do ...
