There was a recent thread where the purpose of isoamyl alcohol in
minipreps was discussed. Reportedly, it was a antifoaming agent if I
recall correctly. 1 part in 25 is the amount used and I would assume it
to be compatable... perhaps a long shot. but adding the alcohol to your
buffer and doing the mixing can take what,, 2 minutes?
