FAQ
What is TBE buffer (10X) and how is it used in molecular biology?
TBE buffer (Tris-Borate-EDTA) is a common buffer used in molecular biology applications such as gel electrophoresis, DNA and RNA agarose and polyacrylamide gel electrophoresis. It provides the necessary ions and pH levels to help DNA or RNA to migrate through the gel based on size. TBE buffer also helps to maintain the stability of nucleic acids during electrophoresis.
What is the composition of TBE buffer (10X)?
TBE buffer (10X) typically contains Tris base, boric acid, and EDTA. The concentration of these components may vary slightly depending on the manufacturer, but a common recipe for 10X TBE buffer is 0.89 M Tris base, 0.89 M boric acid, and 0.02 M EDTA, adjusted to a pH of around 8.3.
How is TBE buffer (10X) prepared for use in experiments?
To prepare a working concentration of TBE buffer, 1X TBE can be made by diluting the 10X stock solution with distilled water. The typical dilution ratio is 1 part of 10X TBE buffer to 9 parts of distilled water. For example, 100 ml of 10X TBE buffer can be diluted with 900 ml of distilled water to make 1 liter of 1X TBE buffer.
What are the advantages of using TBE buffer in molecular biology experiments?
TBE buffer is preferred by many researchers due to its ability to provide stable and predictable electrophoretic conditions. It has a wide range of applications, from routine DNA and RNA electrophoresis to more specialized techniques such as southern and northern blotting. TBE buffer is also known for its compatibility with a variety of gel types, making it a versatile choice for many molecular biology experiments.
Are there any precautions or considerations to keep in mind when using TBE buffer?
While TBE buffer is generally considered safe to use, researchers should be cautious when handling concentrated solutions, as they may be irritants to skin and eyes. It is recommended to wear personal protective equipment, such as gloves and goggles, when handling TBE buffer. Additionally, TBE buffer should be stored properly at room temperature and protected from light to maintain its stability and effectiveness.
