Looking at the bands qualitatively, I would say there is no significant difference between 30 min, 1 hr, and 2 hr incubation times. However, it does appear that quite a bit of DNA is lost in the Ethanol precipitation. On Monday I'm going to test the Ethanol precipitation against the ssDNA column prep that I bought previously.
