Purifying DNA from gel slices

[Alison Reavley]

Hi, I'm looking for a method of purifying plasmid DNA from gel slices
which does not involve phenol or any increase in temperature.  At the
moment I am trying electroelution but find that I am precipitating agarose
as well as DNA after the elution.  I need to get rid of this agarose again
without phenol or heating. I have also tried using Quiagen Qiaquick Gel
Extraction columns but have been frustrated by the small yield and I am
now using concentrations of DNA above those recommended in the protocol. 

Any suggestions?
