Product Information

Hematoxylin is a naturally occurring compound derived from the logwood tree, known for its vital role in histology and microscopy. This versatile dye is primarily used as a staining agent in biological and medical laboratories, allowing researchers to visualize cellular structures and tissues under a microscope. Its ability to bind to nucleic acids makes it particularly valuable for staining DNA and RNA, facilitating the study of cell morphology and pathology. Hematoxylin is often used in conjunction with eosin, creating a contrasting stain that enhances the visibility of tissue samples, making it an essential tool in histopathology and diagnostic medicine.

In addition to its applications in histology, Hematoxylin is also utilized in various industries, including food and cosmetics, where it serves as a natural colorant. Its unique properties, such as its ability to produce a rich blue-black color upon oxidation, distinguish it from synthetic dyes, offering a more environmentally friendly alternative. Researchers and industry professionals appreciate Hematoxylin for its reliability, effectiveness, and the clarity it brings to microscopic examinations, making it a staple in laboratories worldwide.
