I have had the best success using Lambda Sorb. I've tried 4 or 5 methods
from Maniatis and the Red Book and other sources and found LambdaSorb to
yield much better amounts and gives DNA which can be restriction digested.
Other methods I have tried do not yield much DNA which is clean enough to
cut with enzymes.

Be sure and follow the product instructions and use agarose plates and not
agar plates.


Good luck
