It is very difficult to determine the cause of such a problem if the method has not been followed exactly (Gordon & Sweets method, kidney). Special stains are generally the non-routine stains applied to histological sections or cytological preparations, able to show specific tissue components, to differentiate cell types and de- tect the presence of any microorganisms.

This step was overlooked when section B was being stained. The complexity of some stains also works against the uses of automation. This stain uses carbol-fuchsin to stain the lipid walls of acid fast organisms such as M. tuberculosis. If the structure/substance we are staining for is not visible in a slide, we assume it is not present.. For all methods, the level of staining is assessed by looking at the slide with the naked eye. These methods were sometimes also included as members of the special stains family. Optimal tissue embedding is essential for smooth sectioning and ribboning. In a clinical histology laboratory, all specimens are initially stained with H&E and special or advanced stains are only ordered if additional information is needed to provide a more detailed analysis, for example to differentiate between two morphologically similar cancer types. 76{0qej@>\NY{TJ}Fs\8#P%}rcf,6JY0"g Built on 145+ years of market-leading microtomes, Leica Biosystems offers the next generation of microtomes specially designed for research and industry.

Figure 9: Modified GMS Silver Stain (Left: Pneumocystis, lung) (Right: Aspergillus infection, lung). They are quick to produce, but typically do not create the same section quality of as the paraffin technique.. This autonomic ganglion from the myenteric plexus, located between the smooth muscle layers of the muscularis externa of the small intestine, contains ganglionic neurons that show well-defined basophilic Nissl substance (aggregations of endoplasmic reticulum and ribosomal RNA) in their cytoplasm.

This means that a tissue component stains a different color than the dye itself. The section is fixed immediately before it begins to decay and is then stained. Special stains use a variety of dyes and techniques to stain particular tissues, structures or pathogens (such as bacteria) to The term special stains has long been used to refer to a large number of alternative staining techniques that are used when the H&E does not provide all the information the pathologist or researcher needs. Vibrating microtomes (Vibratomes) by Leica Biosystems help you to accurately cut tissue under physiologial conditions without freezing or embedding. Developed in-house with 20+ years of experience, these robust antibodies are optimized for automated and manual applications. [1995], Taxonomy and Biology of Sipunculans, with Emphasis on the Morphology of Phascolion Strombus (Montagu, 1804).
