Precipitation of DNA with Isopropanol - Molecular Cloning
WebIn addition, as an example of the hydrophilic organic solvent in step b), ethanol may be used. At this time, ethanol is preferably added slowly in a volume ratio of 1 to 3 times that of the supernatant using cooled 80 to 100% (v/v) ethanol and reacted at low temperature for 12 to 24 hours to precipitate the precipitate. WebJul 28, 2024 · The total DNA concentration of precipitated pellet plus the suspending solution is about 1150 ng µL −1 at 10% ethanol and about 1100 ng µL −1 at 30% ethanol. It is almost the same to the original DNA concentration 1200 ng µL −1. The slight loss comes from insufficient dissolution.
