TAE Buffer

This buffer is used as both a running buffer and in agarose gel. Its use in denaturing gradient gel electrophoresis methods for broad-range mutation analysis has also been described.

TAE has been used at various concentrations to study the mobility of DNA in solution with and without sodium chloride. 

High concentrations of sodium chloride (and many other salts) in a DNA sample retard its mobility. This may lead to incorrect interpretations of the resulting DNA banding pattern.

Compared with TBE buffer, TAE buffer offers advantages in subsequent enzymatic applications for the DNA sample. For example, if a DNA sample is going to be used in a cloning experiment, the step that follows its running on an agarose gel is to ligate to a cloning vector.

A DNA sample from a TAE gel is suitable for this purpose, while DNA from a TBE gel is not, because borate in the TBE buffer is a strong inhibitor for many enzymes.
