I still have problems with DNA quality caused by phenols, till I integrated two methods, CTAB for homogenizing and silica filter for purification, and it works. Is there an alternative method?

I had a crystal hit in a well with 0.1M HEPEs pH 7.5, 10%(w/v) PEG 4000, and 20%(w/v) isopropanol. Why is isopropanol in w/v here if it's just solvent? How do I recreate this well condition?
