3) Don't wash with 70% ethanol.
How can not washing with 70% ethanol increase the yield of a DNA prep? I
was under the impression that DNA was not soluble in 70%. Sometimes I wash
samples twice with 70% ethanol and have never noticed a loss in expected
yield. I have done about 25 qiagen midipreps and only had a problem when I
overloaded the with DNA, judged by looking at the supernatant from different
steps after the failure. Maxipreps might however behave differently.
