Ethidium bromide CAS:1239-45-8 Manufacturer Price

Ethidium bromide is commonly used as a nucleic acid stain in molecular biology research. It is used to visualize DNA and RNA in techniques such as gel electrophoresis. When added to a DNA or RNA sample, ethidium bromide intercalates between the base pairs of the nucleic acids, allowing them to be visualized under ultraviolet light as fluorescent bands. This staining technique helps researchers to analyze and identify DNA and RNA fragments in a sample.
