Is it possible to use glycerol DNA/RNA drying during extraction?
if glycerol residues stay in DNA, it might interact with later PCR. Overdrying is an underestimated issue and often DNA resuspension is not only long (>3h) but also very partial even after one night resuspension. it is not possible to evaporate ethanol first but reaching the point where sample are still wet but ethanol mostly removed is the best option
