Either ethanol or isopropanol can be used to achieve this purpose; however, the use of ethanol is generally preferred. Cations, provided as …
How Phenol Extraction of DNA Works: An Easy Explanation
Weborganic phase can be saved for subsequent DNA and protein extraction. C. RNA Precipitation 1. Add 0.5 mL of isopropanol per 1 mL of TRIzol reagent originally used to a new tube. 2. Transfer the aqueous phase to the labeled isopropanol tube. Precipitate the RNA from the aqueous phase by pipetting up and down gently. (Do not vortex.) 3. WebNucleic acids are less soluble in isopropanol than in ethanol, so you will get better precipitation of low RNA concentrations with isopropanol. HOWEVER, isopropanol is also better at... maggie mitchell actress
