FAQ
What is TBE buffer (10X) used for?
TBE buffer (Tris-Borate-EDTA) is commonly used in nucleic acid electrophoresis applications, including DNA and RNA agarose and polyacrylamide gel electrophoresis, as well as northern and Southern blotting techniques. It provides the necessary ionic environment for nucleic acids to migrate through a gel matrix based on their size and charge.
How is TBE buffer prepared from the concentrated 10X stock solution?
To prepare 1X TBE buffer from the concentrated 10X stock solution, you would dilute it with deionized water at a ratio of 1:10. For example, if you need to make 1 liter of 1X TBE buffer, you would mix 100 ml of the 10X stock solution with 900 ml of deionized water. Make sure to mix the solution well to ensure uniformity.
What are the advantages of using TBE buffer over other electrophoresis buffers?
TBE buffer is preferred over other electrophoresis buffers like TAE (Tris-Acetate-EDTA) for several reasons. TBE buffer has a higher buffering capacity, which helps maintain a stable pH during electrophoresis and allows for sharper band resolution. Additionally, TBE buffer has a higher conductivity, resulting in faster migration of nucleic acids through the gel matrix.
How should TBE buffer be stored to maintain its stability and effectiveness?
TBE buffer should be stored at room temperature, away from direct sunlight and sources of heat. It is important to keep the container tightly sealed to prevent evaporation and contamination. Proper storage conditions help maintain the stability and effectiveness of the buffer for an extended period.
Can TBE buffer be used for other applications besides nucleic acid electrophoresis?
While TBE buffer is primarily used for nucleic acid electrophoresis applications, it can also be used in other laboratory techniques that require buffering and conductivity properties. Some researchers have reported using TBE buffer in protein electrophoresis and as a running buffer for capillary electrophoresis systems.
