SPECIAL STAINS AND ITS APPLICATIONS IN H and E is the most commonly used stain in the pathology laboratory. Timing is always approximate. It covers a wide variety of methods that may be used to visualize particular tissue structures, elements, or even microorganisms not identified by H&E staining. in Histopathology Even when advanced staining methods are used, the H&E stain still forms a critical part of the diagnostic picture as it displays the underlying tissue morphology which allows the pathologist/researcher to correctly interpret the advanced stain. 0000021342 00000 n This an all-around useful stain for many things. Stain Identifies neutral lipids and fatty acids in smears and tissues. The process is more time-consuming than creating frozen sections, but provides better quality staining in most cases and the resultant samples (referred to as blocks) can be stored almost indefinitely. Bacilli are rod-shaped bacterial organisms. Be aware of the effect of the microscope setup on the appearance of un-coverslipped (wet) sections; it can produce the appearance of false background staining. Meet the challenge with solutions engineered to address todays needs and tomorrows opportunities. Figure 10: Periodic Acid Schiff (kidney). Special Stains - Department of Pathology and Laboratory Medicine 4.2.1. 0000016581 00000 n From translational research to routine diagnostics or AI development, there is an Aperio scanner for every need.

Advancing Cancer Diagnostics, Improving Lives, An Introduction to Routine and Special Staining, Figure 1: A microtomist creating a ribbon of very thin sections for staining, Figure 2. Gram positive organisms usually stain well, but gram negatives do not (because the lipid of the bacterial walls is removed in tissue processing). 18 0 obj <> endobj xref 18 41 0000000016 00000 n It is very difficult to determine the cause of such a problem if the method has not been followed exactly (Gordon & Sweets method, kidney). The choice of Clinical or Research Microtomes from Leica Biosystems gives the precision, control, and comfort needed to get the best possible section from every block, every day. The process for frozen section preparation is as follows: When paraffin sections are to be prepared the specimen is first preserved with a fixative and then the tissue structure is supported by infiltrating the specimen with paraffin wax.

Access additional educational resources to support your applications, including content with technical knowledge and "how-to" guides. These methods were sometimes also included as members of the special stains family. Hematoxylin is extracted from the logwood tree and purified. WebThis book provides detailed information on basic and advanced laboratory techniques in histopathology and cytology. Section A shows red smooth muscle. Others are light sensitive and require storage in the dark. Effective image management and automated systems communication are essential for digital pathology success. In the histopathology laboratory, the term routine staining refers to the hematoxylin and eosin stain (H&E) that is used routinely with all tissue specimens to reveal the underlying tissue structures and conditions.
