Precipitate at -20 0C for 1 hour or overnight or -80 0C 1 hr (overnight will give more precipitation if RNA amount is low) 3. Centrifuge at full speed (13000rpm), 40C for 30 mins. 4. WebFeb 8, 2024 · Add either ethanol or isopropanol to precipitate the plasmid DNA. Either spin to pellet the DNA or apply the solution to a column that will bind the now precipitated DNA. Wash the pellet or column with 70% ethanol to remove excess salt. Resuspend the DNA pellet, or elute the DNA off of the column using water or a neutral buffer such as TE.
