Hematoxylin
Hematoxylin is a natural dye used in pathology to stain tissue samples, making cells and their structures visible under a microscope. Derived from the heartwood of the logwood tree, it binds to cell components rich in DNA and RNA, such as the nucleus, imparting a blue or purple color. This staining helps scientists and doctors differentiate between different cell types and identify abnormalities, providing essential information for diagnosing diseases. Hematoxylin is often combined with other stains to enhance tissue analysis, serving as a fundamental tool in histology and pathology laboratories.
