Frequently asked questions
How do I dilute 5X TBE?
For the common 0.5X running strength, mix 1 part BZ209 with 9 parts high-purity water. For 1X, mix 1 part with 4 parts water. Use the same dilution for the gel and the tank.
Why choose 5X TBE instead of 10X?
5X TBE is less likely to precipitate during storage than 10X TBE, so it is easier to keep ready on the bench. Both give the same working buffer after dilution.
Is TBE suitable for gel extraction?
TBE works well for analysis, but borate can inhibit enzymes used after gel extraction. For DNA recovery and cloning, use TAE (BZ208).
What is the pH of the TBE buffer?
About pH 8.3 at working strength, the standard value for Tris-borate-EDTA running buffer.
How should 5X TBE be stored?
Store at 2–30 °C, tightly closed. Unopened bottles have a 1-year shelf life and ship at room temperature.
