Hematoxylin and eosin stain (or haematoxylin and eosin stain or hematoxylin-eosin stain; often abbreviated as H&E stain or HE stain) is one of the principal tissue stains used in histology. It is the most widely used stain in medical diagnosis and is often the gold standard. For example, when a pathologist looks at a biopsy of a suspected cancer, the histological section is likely to be stained wit… WebJohn D.

WebIt has the appearance of small, colorless-grayish or slightly yellow-green crystals, with melting point 89 °C (24 H2O hydrate). It is odorless and soluble in water (200 g/100 ml). It is not especially toxic, but is a mild acidic irritant. The compound is known by a variety of names and acronyms (see 'other names' section of infobox). WebThe pH of Mayer's haematoxylin solution was 2.31. CONCLUSIONS To find CPPD crystals in the paraffin sections of articular tissues, the staining period with Mayer's haematoxylin should be limited to three minutes. The longer the staining period, the greater the reduction in the number of crystals owing to the strong acidity of the haematoxylin ... train from nyc to montauk
