i think the difference between isopropanol and ethanol precipitation
has got something to do with the solubility of salt.salts are probably
less soluble in isopropanol than ethanol and that is why i guess u
give a 70% ethanol wash to remove salts after precipitaion and not
70%isopropanol!!! this is just my
hope it helps.
