Have a word with QIAGEN about doing a plasmid prep from yeast. I looked
into it a while back, and one of their reps gave me an experimental
protocol (one they haven't tested or optimized). It involves a few extra
steps at the beginning, but it uses one of their midiprep columns. Not
sure what kind of yield you get out at the end as i never tried it myself
(i need to separate the two different plasmids in my yeast before
analysing further). Anyway, get in touch with them.
