WebEssentially, hematoxylin is a basic dye and complexes with nucleic acids (DNA and RNA in the nucleus; RNA in the cytoplasm) or other negatively charged molecules (such as sulfate groups). Structures that bind hematoxylin are therefore termed "basophilic" (base loving). WebHematoxylin is a basophilic dye extracted from the tree Heamatoxylum campechianum. It specifically binds to acidic compounds and thus is useful for staining cell nuclei which contain acidic substances: DNA and RNA. Hematoxylin, when oxidized forms hematein, which has thick pale blue purple colour.
