Definition of «ethidium»

Ethidium is a chemical compound that has been used as a DNA stain in molecular biology research. It intercalates between the base pairs of double-stranded DNA, binding to the minor groove and causing a strong fluorescence signal when exposed to ultraviolet light. This makes it possible for scientists to visualize and analyze DNA samples under a microscope or other imaging techniques.
