WebPrincipally used as a nuclear stain (to stain the cell nucleus), haematoxylin will also stain rough endoplasmic reticulum, ribosomes, collagen, myelin, elastic fibers, and acid mucins. [10] Haematoxylin alone is not an effective stain, but when oxidized to hematein, and combined with a mordant, stains chromatin in cell nuclei dark blue to black. 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 Figure 4-43.These complexes strongly bind to DNA and RNA, which indicates that it has some carcinogenic properties.
