Haematoxylin - Wikipedia
WEBHaematoxylin or hematoxylin (/ ˌ h iː m ə ˈ t ɒ k s ɪ l ɪ n /), 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 16 H 14 O 6.
H&E stain - Wikipedia
WEBHematoxylin 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. [1] [2] [3] It is the most widely used stain in medical diagnosis [1] and is often the gold standard . [4]
Haematoxylin - an overview | ScienceDirect Topics
WEBHematoxylin is a small organic compound extracted from a tree that forms strong complexes with certain metal ions, such as iron. Its structure is shown in Fig. 4.43 . These complexes strongly bind to DNA and RNA, which indicates that it has some carcinogenic properties.

Hematoxylin-Eosin | SpringerLink
WEBNov 25, 2022 · Principle. Hematoxylin-eosin staining is based on the affinity of two dyes, hematoxylin and eosin, to tissue components and structures, due to their pH value. Hematoxylin is a basic “nuclear” dye which has affinities for acidic structures, such as DNA, RNA, cell membrane proteins, and elastin.
