This is a staining method to illustrates mineralization such as calcium and potassium in tissues. [1] [2] [3] [4] [5]It is a precipitation reaction in which silver ...
Tissue image cytometry or tissue cytometry [1] is a method of digital histopathology and combines classical digital pathology (glass slides scanning and virtual slide generation) and computational pathology (digital analysis) into one integrated approach with solutions for all kinds of diseases, tissue and cell types as well as molecular markers and corresponding staining methods to visualize ...
The most commonly used stain in histology is a combination of hematoxylin and eosin (often abbreviated H&E). Hematoxylin is used to stain nuclei blue, while eosin stains the cytoplasm and the extracellular connective tissue matrix of most cells pink. There are hundreds of various other techniques which have been used to selectively stain cells.
Phosphotungstic acid-haematoxylin staining demonstrating contraction band necrosis in an individual who had a myocardial infarction (heart attack). Phosphotungstic acid haematoxylin ( PTAH ) is a mix of haematoxylin with phosphotungstic acid , used in histology for staining .
Immunohistochemistry can be performed on tissue that has been fixed and embedded in paraffin, but also cryopreservated (frozen) tissue.Based on the way the tissue is preserved, there are different steps to prepare the tissue for immunohistochemistry, but the general method includes proper fixation, antigen retrieval incubation with primary antibody, then incubation with secondary antibody.
Histopathology – the microscopic examination of stained tissue sections using histological techniques. The standard stains are haematoxylin and eosin, but many others exist. The use of haematoxylin and eosin-stained slides to provide specific diagnoses based on morphology is considered to be the core skill of anatomic pathology.
Another common variant is the Masson trichrome & Verhoeff stain, which combines the Masson trichrome stain and Verhoeff's stain. [2] This combination is useful for the examination of blood vessels ; the Verhoeff stain highlights elastin (black) and allows one to easily differentiate small arteries (which typically have at least two elastic ...
Methyl green-pyronin (MGP) is a classical histological staining technique using two basic (cationic) dyes for the demonstration and differentiation of DNA and RNA. Methyl green is specific for phosphate radicals in the DNA double helix staining it green-blue.
