Dialysis is an easy and efficient, yet cheap and gentle technique to separate biomolecules according their molecular weight. It is associated or not to other purification methods, serving typically to desalt samples, in biochemistry works as well as before analysis (sample preparation for bioassays, release or binding studies).
