Supplier: VWR

Ethidium Bromide solution is a fluorescent stain for visualizing nucleic acids in solution or in electrophoresis gels. At a concentration of 0.5 µg/ml, ethidium bromide is useful in agarose or acrylamide ges for band detection. It is used to detect as little as 10 ng of nucleic acid. At high concentrations (0.5 - 1.0 µg/ml), it may be used to facilitate purification of DNA in cesium chloride gradient.

For centuries, humans have used selective breeding and conventional hybridization to produce desirable qualities and to increase crop yields. Today, scientists use genetic engineering to directly manipulate the DNA, quickly producing these desirable traits. In this experiment, students will use agarose gel electrophoresis to explore the molecular methods used by scientists to identify genetically modified organisms. No thermal cycler is required. Students are also encouraged to explore the controversy surrounding the use of genetically modified organisms.
