1. Never expect to isolate a large amount Plasmid DNA from yeast.
2. What I did is:
Incubate lytic enzyme with your yeast for an hour. Then followed the
BioRad kit miniprep protocol, start from lysis solution (equal to solutionII
in classical protocol). I guess kits from other companies are also work.
At the end, elute your DNA from matrix with 20microliter of TE instead of 100
microliter. One microliter of such extract is sufficient for a bacteria
transformation, even though it's CEN plasmi
