While many larger laboratories do useautomated instrumentsfor the more common stains, they still have an area for hand staining. They are quick to produce, but typically do not create the same section quality of as the paraffin technique.. The paraffin section process is as follows: Hematoxylin and Eosin (H&E) stainingis used routinely in histopathology laboratories as it provides the pathologist/researcher a very detailed view of the tissue.

The pH of this stain can be adjusted to give more specificity. The variety of stains also means that special staining is not as automated as H&E staining. Secure, scalable solutions with flexible deployment options enable anytime, anywhere access to your slides. The most commonly used stain in histology labs is haematoxylin and eosin (or H&E) representing the bread and butter stain for most pathologists who diagnose disease, and for researchers who work with many tissue types. 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. Special Stains There are a variety of staining procedures used to identify specific external or internal structures that are not found in all bacterial species, such as a capsule stain and a flagella stain. Trichrome will also aid in identifying normal structures, such as connective tissue capsules of organs, the lamina propria of the gastrointestinal tract, and the bronchovascular structures in the lung.
