Jim and and other netters,

This is something that I have always done, but not known the reason why it is 
so.  Could you please enlighten me as to the reason one should prepare LMP 
agarose gels in TAE instead of TBE when purifying DNA fragments from the gel.  
(I also always use TAE gels for Southern blotting to nylon membranes).

Thanks for your help.
