Recipes
for 2 liter of standard 5X TBE Buffer:
108g Trizma base + 55g Boric acid + 40mls 0.5M EDTA (pH 8.0)
Simplified method to
make 2 liter of the standard 5x TBE buffer:
Use a 2000ml
bottle, add about 1200ml dd-water and put a stir bar into the bottle to
mix
108g Trizma base + 55g Boric acid + 40mls 0.5M EDTA (pH 8.0), then
bring final volume to 2000ml with additional dd-water. There is no need
to adjust pH of the final 10x TBE buffer stock solution.
Prepared 5x
TBE buffer stock solution can be stored at room temperature for a period
of time. Precipitation will form at bottom of the storage bottle.
Precipitated 5x TBE buffer stock should be disposed. Please note, Trizma
base is a brand name of Tris-base.
Tips:
Among the
three components of 5x TBE buffer, EDTA should be prepared as 0.5M stock
solution with pH adjustment to 8.0, which takes some time and skill. For
your convenience, here is further
reading for preparation of 0.5M EDTA stock solution.

" The Liberty bufferless gel
system in dd-water is the best gel electrophoresis
system we've ever used. It's not only easy to set up,
robust, and fast, but generates excellent results
without the need of running buffer. Highly
recommended." ---- Ivan Delgado Orlic, President
and CEO, Mouse Genotype Co. |

The
problems of your TBE gel system:
Diagram
above shows traditional submarine gel electrophoresis. 1x
running buffer, a highly conductive liquid, has two functions:
keeping the agarose gel cooled and conducting electric current.
To
avoid gel overheating and band smiling, the volume of running
buffer should be as large as possible. But more buffer conducts
more electric current, which generates more heat. So buffer
volume should be as small as possible. Which
is correct - more buffer or less buffer?
