GUIDELINES FOR HEMATOXYLIN & EOSIN STAINING

Haematoxylin or hematoxylin , also called natural black 1 or C.I. 75290, is a compound extracted from heartwood of the logwood tree (Haematoxylum campechianum) with a chemical formula of C 16H 14O 6. This naturally derived dye has been used as a histologic stain, ink and as a dye in the textile … Visa mer Haematoxylin has been synthesized, although never in commercially viable amounts. Historically the logwood was exported and the haematoxylin extracted in Europe, more recently extraction takes place closer to where … Visa mer Haematoxylin was first used as a dye by the Mayans and Aztecs in Central America where logwood trees grow natively. The dye was first … Visa mer • Staining (biology) • Histology • Eosin • H&E stain • Haematein • Verhoeff's stain Visa mer Haematoxylin stain is commonly followed (or counterstained) with another histologic stain, eosin. When paired, this staining procedure is known as H&E staining, and is one of the most commonly used combinations in histology. Haematoxylin is also a component of … Visa mer Haematoxylin has been used as the primary component of writing and drawing inks, although the timing of first use as an ink is unclear.
