Product Description


  • Ethidium Bromide Solution can be used to detect both single and double stranded nucleic acids (both DNA and RNA). However, Ethidium bromide ( EtBr ) does not intercollate into single-stranded DNA very well; therefore, the fluorescence of single-stranded DNA is relatively poor in comparison to double-stranded DNA.
  • Use 2.5 µl of ethidium bromide solution for every 50 ml of molten agarose, running buffer, or staining solution which is about one drop.
  • The recommended final concentration of Ethidium Bromide in an agarose gel and/or electrophoresis buffers is 0.5µg/ml.
  • How do I make a stock solution with a concentration 0.5 µg/ml? Add one drop (approximately 50 µl) of IBI 10 mg/ml Ethidium Bromide Solution to 1-liter of DDI water to make a stock solution with a desired concentration of 0.5 µg/ml. This stock solution of ethidium bromide can then be added to the researcher’s agarose or buffer solution.
