I am always finding that y'all go to the trouble to dry your nucleic acid
precipitates "down" with a "Speed-Vac". Next time rinse your pellet with
70% ethanol and set it upside down in a 50-60 C oven for five minutes.
You don't need a cannon to swat a fly. We don't even have a "Speed-Vac"
and have been doing nucleic acid work without one for twenty years. Besides
overdrying samples by this method leads to reduced recovery, and in fact
denatures short DNA fragments.
