WebMay 19, 2024 · Isopropanol/ethanol is used in precipitation of DNA, which breaks the hydration shell. Isopropanol is a good choice for precipitation of DNA. The amount of isopropanol requirement is less (0.6–0.7 volume of supernatant), as isopropanol has a higher capacity to reduce the dielectric constant of water than the ethanol (2–3 volume) … WebApr 10, 2024 · Precipitate your sample (s). You can use either Isopropanol or Lithium Chloride for this step. Isopropanol (Option A) - Add 1 volume of Isopropanol to the extracted aqueous layer. Incubate at -20°C for 1 hour. Lithium Chloride (Option B) - LiCl selectively precipitates RNA versus DNA or proteins.
WebWhen phenol is mixed with the aqueous solution containing DNA, proteins will move into the phenol phase and will be separated from the aqueous DNA. Add either 700 μL of cold 100% ethanol or 350 μL room temperature isopropanol to the solution to precipitate the plasmid DNA; see detailed protocol below .
