How to isolate proteins
acid removal is not necessary; the precipitate may also bind the protein of interest]. 2. Precipitation of proteins: Several methods are available for precipitation of proteins utilizing changes in pH and temperature, or addition of salts and organic solvents. Ammonium sulfate is the most commonly used precipitant for salting out of proteins. At
