Leírás

Általános leírás

Tris Acetate-EDTA (TAE) buffer, with a pH range of 8.1 – 8.4, is typically used for agarose gel electrophoresis, especially for the recovery of DNA. For larger double-stranded DNA fragments (>12kB) TAE buffer is preferred. However, the buffering capacity can become exhausted if electrophoresis time is extended. Buffer circulation or replacement during electrophoresis can remedy the lower buffering capacity.

Alkalmazás

Suitable as a running and gel preparation buffer in:

• DNA agarose gel electrophoresis
• Non-denaturing RNA agarose gel electrophoresis for RNA >1500 bases
• Denaturing gradient gel electrophoresis
• Northern and Southern blotting

TAE running buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during extended electrophoresis. Buffer circulation or buffer replacement during extended electrophoresis can remedy the lower buffering capacity. Dilution of the concentrated TAE buffer produces a 1× TAE buffer with 40 mM Tris-acetate and 1 mM EDTA, pH 8.3. The 1× TAE buffer is used both in the agarose gel and as a running buffer. Applied voltages of less than 5 V/cm (distance between the electrodes of the unit) are recommended for maximum resolution.
